Copper and manganese extraction through leaching processes
No full text[SPA] Esta tesis doctoral se presenta bajo la modalidad de compendio de publicaciones. Esta Tesis se centra en la recuperación de Cu y Mn desde cuatro posibles minerales estratégicos para la minería chilena y mundial: los nódulos de manganeso marinos, los óxidos de cobre negros, la calcosina y la calcopirita. Este es uno de los ejes de desarrollo de la industria minera en el sector del cobre que, ante el descenso de leyes y el aumento del consumo, busca nuevas fuentes de abastecimiento, recuperación de otros metales y subproductos y emplear, para los procesos industriales de tratamiento mineral, las sustancias de desecho en otros sectores como el de la desalinización de agua o la industria siderúrgica. Se analizan las condiciones de disolución de los metales procedentes de estos minerales utilizando la técnica de lixiviación forzada a escala de laboratorio. Se evalúa el uso de diferentes aguas para la solución lixiviante, como el agua de mar y la salmuera de descarte en las plantas desalinizadoras, probando el uso de diferentes agentes oxidantes en base al hierro y manganeso. Bajo las mismas condiciones de trabajo, se obtienen resultados similares para la disolución de Mn desde MnO2 presente en nódulos de manganeso y cobres negros. Por lo cual, se presume es posible replicar procesos previos en nódulos de manganeso para los minerales de cobre negro que se desechan en la gran minería en Chile, siendo el tiempo de curado un parámetro muy importante a considerar, ya que al trabajar en tiempos prolongados (sobre 48 h) se puede trabajar a bajas concentraciones de NaCl, y a la vez incrementar de forma significativa la extracción de Cu por la previa disolución de MnO2. Por otra parte, la combinación de aditivos entre agua residual de plantas desalinizadoras y MnO2 en el sistema, se presenta como una alternativa que incrementa la disolución de Cu desde minerales sulfurados a temperatura ambiente en la literatura actual, esto debido a que permite trabajar a altos valores de potencial en el sistema.[ENG] This doctoral dissertation has been presented in the form of thesis by publication. This Thesis are focused on the recovery of Cu and Mn from four possible strategic minerals for Chilean and worldwide mining: marine manganese nodules, black copper oxides, chalcocite and chalcopyrite. This is one of the main development axes of the mining industry in the copper sector given the decline in grades and increased consumption. Mining enterprises are seeking new sources of supply, recovery of other metals and by products and also employ waste substances from other sectors for industrial processes of mineral treatment, such as brine from water desalination or the steel industry wastes. The dissolution conditions of the metals from these minerals are analyzed using the vat leaching technique on a laboratory scale. The use of different waters for the leaching solution is evaluated, such as seawater and waste brine from desalination plants, testing the use of different oxidizing agents based on iron and manganese. Under the same working conditions, similar results are obtained for the dissolution of Mn from MnO2 present in manganese nodules and black coppers. Therefore, it is presumed possible to replicate previous processes in manganese nodules for black copper minerals that are discarded in large mining in Chile. Being a very important parameter to consider the curing time, since when working for long times over 48 h) it is possible to work at low concentrations of NaCl, and at the same time significantly increase the extraction of Cu by the previous dissolution of MnO2. On the other and, the combination of additives between wastewater from desalination plants and MnO2 in the system, is presented as the alternative that most increases the dissolution of Cu from sulphide minerals at room temperature in the current literature, this because it allows working at high potential values in the system.Escuela Internacional de Doctorado de la Universidad Politécnica de CartagenaPrograma de Doctorado en Tecnología y Modelización en Ingeniería Civil, Minera y AmbientalEsta tesis doctoral se presenta bajo la modalidad de compendio de publicaciones.

Joint Select Committee on Constitutional Recognition of Aboriginal and Torres Strait Islander Peoples: final report
No full textOn 28 November 2012, the Parliament agreed that a Joint Select Committee on Constitutional Recognition of Aboriginal and Torres Strait Islander Peoples be appointed to inquire into and report on steps that can be taken to progress towards a successful referendum on Indigenous constitutional recognition.
Chair\u27s foreword
For the last 114 years, Australia\u27s founding document, the Constitution, has been silent on Aboriginal and Torres Strait Islander peoples.
Excluded from voting, and from participating in the convention debates which led to the drafting of the Constitution, the voices of Aboriginal and Torres Strait Islander peoples were silenced by the framers of the Constitution.
While there is no constitutional recognition for Aboriginal and Torres Strait Islander peoples, that silence will continue. The absence of Aboriginal and Torres Strait Islander peoples from the Constitution makes silent and renders invisible the world\u27s oldest continuing culture.
European contact began in the 1600s when ships from Europe first explored the coastlines of the lands and waters that would become known as Australia.
In 1770, Captain James Cook made landfall at Botany Bay. On 26 January 1788, Captain Arthur Phillip established a settlement at Sydney Cove made up of those who travelled as part of the First Fleet.
Over the next century, new colonies were founded and borders were drawn up across a continent that had been home to hundreds of Aboriginal nations for tens of thousands of years.
When the Constitution was drafted, the exclusion of Aboriginal and Torres Strait Islander peoples was unremarkable for the time, as Aboriginal and Torres Strait Islander peoples were not considered citizens and had minimal rights and protections.
However, the continued constitutional silence maintained by this exclusion is remarkable.
That our Constitution allows a state to ban a race from voting is remarkable.
That in our Constitution there are more references to lighthouses than to the first
peoples of this nation is remarkable.
That constitutional recognition has not occurred already is remarkable.
The Joint Select Committee on Constitutional Recognition of Aboriginal and Torres Strait Islander Peoples has engaged the Australian community on constitutional recognition by conducting fifteen public hearings, speaking with constitutional law experts and holding community forums. At all times, the committee has sought to hear the aspirations of Aboriginal and Torres Strait Islander peoples. The committee strongly believes that in order to achieve constitutional recognition, the support of Aboriginal and Torres Strait Islander peoples is of critical importance. Without this support, the imposed silence of the past will continue into the future.
The committee has heard that it is time to remedy the injustice of exclusion and recognise in our founding document the significant contribution of Aboriginal and Torres Strait Islander peoples to a modern Australia.
The committee heard that in order to achieve this, the mere removal of racist sections of the Constitution would not be enough and that much more is needed. The committee heard that Aboriginal and Torres Strait Islander peoples will accept nothing less than a protection from racial discrimination in the Constitution.
Since the time of Captain Cook\u27s first landfall, Aboriginal and Torres Strait Islander peoples have suffered from continuous dislocation, discrimination and disadvantage.
The committee heard of the serious and pressing issues faced by Aboriginal and Torres Strait Islander peoples in everyday life and heard of the endemic racial discrimination faced by Aboriginal and Torres Strait Islander peoples.
The committee acknowledges that recognition in the Constitution will not end racism in Australia, nor will it be a solution to the serious problems faced by Aboriginal and Torres Strait Islander peoples. However, constitutional recognition will be a vital step towards reconciliation and give a voice to Aboriginal and Torres Strait Islander peoples in a Constitution better aligned with a modern Australia.
By protecting Aboriginal and Torres Strait Islander peoples from discrimination on the basis of race, Australia will be better placed to offer its first peoples a future in which their historical mistreatment is not repeated.
This final report of the Joint Select Committee on Constitutional Recognition of Aboriginal and Torres Strait Islander Peoples recommends that a referendum be held on the matter of recognising Aboriginal and Torres Strait Islander peoples in the Constitution.
I commend this report of the Joint Select Committee on Constitutional Recognition of Aboriginal and Torres Strait Islander Peoples to the Prime Minister and the Australian Parliament.

David Zimmer Christmas letter
No full textThis Christmas letter written November 30, 1999, by David Zimmer is titled "Season's Greetings from the last of the Red-Hot-Santas!" It features an illustration of Santa Claus with a guitar, and a summary of Zimmer's year.
David Zimmer (1929-2005) was born in Harrisburg, Ohio. He enlisted in the U.S. Army and served for two years during the Korean War at the Brooke Army Medical Center in San Antonio, where he performed in drag for wounded soldiers. After the war, he returned to Ohio. Zimmer performed as Dolly Divine, a name inspired by the song "Hello Dolly." In 1964, he established the Berwick Ball with Orn Huntington, another important early gay activist in Central Ohio. The Ball began as a formal Halloween costume ball that provided a safe space to gather and enjoy drag shows for the gay community each year; over the years, it grew into an annual Halloween tradition and an important fundraiser for the AIDS movement and other charities. During the 1970s, Zimmer was also known for hosting lavish parties at his Harrisburg home. In 1989, he moved to the German Village area of Columbus where he remained active in the community. During the 1990s, Zimmer continued to perform in and out of drag and commissioned costume designer Dick Frank to make elaborate outfits. Zimmer worked for Huntington National Bank for 39 years and was a member of the Harrisburg United Methodist Church, Veterans of Foreign Wars and the German Village Society
