The Separation Of Copper Sulfide Ore Minerals From Gangue THE SEPARATION OF COPPER SULFIDE ORE MINERALS FROM GANGUE USING MAGNETIC NANOPARTICLES FUNCTIONALIZED WITH PEPTIDES SELECTED VIA PHAGE DISPLAY A PROOF OF CONCEPT by ROBERT CRANDALL GREENE, Simon Fraser University, 2014 A THESIS SUBMITTED IN PARTIAL FULFILLMENT
An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements.
If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.
Davenport, in Encyclopedia of Materials: Science and Technology, 2001. Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an orewater pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Gangue. In mining, gangue is the oft commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.
Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from orecontaining rock to a final product that is the highestpurity commercial metal in existence and used in a wide variety of applications essential to modern living.
In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals.
#0183;#32;Coppercontaining rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue.
These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue
Gangue WikipediaThe separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressing. It is a necessary, and often signific
As nouns the difference between ore and gangue is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which at the time of the rock''s evaluation and proposal for extraction are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials'' presentday economic values while gangue is...
Copper minerals are divided up into three groups Beneficiation is the concentration of ore through separation into desirable mineralthe part of the ore that is useable; and gangue (pronounced gang) 6 Copper mining, Production Wastes and the Environment .
