The solvent extraction separation of molybdenum and copper from acid leach residual solution of Chilean molybdenite concentrate
(1995)
A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
Metal-selective processing from the Los Sulfatos Porphyry-Type Deposit in Chile: Co, Au, and Re recovery workflows based on advanced geochemical characterization
(MDPI, 2020)
Sulfides extracted from porphyry-type deposits can contain a number of metals critical for the global energy transition, e.g., Co and precious metals such as Au and Re. These metals are currently determined on composite ...
Geotechnical characterization of ore related to mudrushes in block caving mining
(South African Institute of Mining and Metallurgy, 2017)
Mudrushes are sudden inflows of mud ore into underground miningfacilities. They may cause harm to people and equipment, productiondelays, dilution of ore, and mine closure. The aim of this work is to charac-terize, by ...
Optimizing open-pit block scheduling with exposed ore reserve
(Southern African Inst Mining Metallurgy, 2016-07)
A crucial problem in the open pit mining industry is to determine the optimal block scheduling, defining how the orebody will be sequenced for exploitation. An orebody is often comprised of several thousand or million ...
In situ mining through leaching: experimental methodology for evaluating its implementation and economic considerations
(The Southern African Institute of Mining and Metallurgy, 2015)
Rising costs in the mining industry have necessitated a search for
alternative methods for the recovery of metals from deposits that are no
longer economically or environmentally exploitable by conventional
mining. These ...
Methodology for evaluation of mud rush risk in block caving mining
(Southern African institute mining metallurgy, 2017)
Mud rushes are sudden inflows of fine wet ore within underground mines; they can harm people and equipment as well as cause production delays. Block and panel caving mines are prone to mud rushes in their production levels, ...
Deconstructing the Leaching Ratio
(Springer, 2020)
The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of ...
Copper extraction from hydrothermal polymetallic ore sources in Meymand cave dwelling village, Iran; An archaeometallurgical approach
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencias, 2013-01-01)
The polymetallic ore intrusion of “Meymand” is situated between three important copper and iron orogeny zones called “Sarcheshmeh”, “Meydook” and “Gol-e Gohar” in the Kerman province, central Iran. The occurrences of ...
Materias primas críticas y complejidad económica en América Latina
(Universidad Pedagógica y Tecnológica de Colombia, 2018-02-06)
There are minerals that boost economic growth and which are essential for the development of sustainable technologies. These critical raw materials (CRMs) were determined by models created for complex economies. This paper ...
