copper slag from gold ore processing

copper slag from gold ore processing. Copper extraction Wikipedia. Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production) Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were,Eliminating Copper from Gold Ore - 911 Metallurgist,11.10.2015· This cuprocyanide is obtained by heating the cupriferous ore with cyanide solution. When the cuprocyanide has dissolved its maximum of copper, part of the copper in the solution is precipitated electrolytically during which a partial regeneration of the cyanide is said to take place. The treated ore is then cyanided in the usual way and the gold recovered by electrolytic precipitation. Whether or not any precious metal was dissolved in the preliminary cyanideGold-Copper Ores - ScienceDirect,01.01.2016· Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron-sulfide minerals. Due to this variable gold association, significant gold is often not recovered with the copper concentrate and treatment of the tails or,

Characterization of Slags Produced During Gold Melting

01.01.2015· In the extractive metallurgy of gold ores the cyanidation and melting processes are generally applied. These processes allow obtaining the “dore”. The slag generated during the melting process presents various characteristics, depending on the mineral source and the type of flux used. The literature information on this pyrometallurgical process at high temperature is very poor. For thisGold Smelting & Refining Process - 911 Metallurgist,28.02.2016· In general, slag from smelting process arises from extraneous materials such as rust and oxides; oxidation of elements in the charge (e.g. iron, copper, zinc); residues from fuels; fluxes employed in the process (silica, borax, sodium nitrate, sodium carbonate, fluorspar); crucible erosion. Then, slag can vary in appearance and chemical composition.(PDF) An Overview of Treatment of Copper-gold Ores,Copper-gold ores prove difficult to treat with conventional cyanide leaching process due to severe interference of copper minerals with cyanide leaching.

Recovery of metal values from copper slag and reuse of,

Copper slag was characterized and processed. The pyro-metallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (e.g., Fe, Cu and Mo) into the iron-rich alloy product which can be a feed material for steel making.

In most instances the matte is transferred directly as a molten liquid to a converter, but it may also be poured into ingots, cooled, and moved to a separate facility. In the converter, more silica is added to the matte and air is blown through the furnace to again melt the,

The environmental impact of gold production

processing. As non-refractory ores become depleted, the ability to recover gold from refractory ores has become more important. For an ore grade (i.e. metal content) of 3.5 gram per tonne of ore, the study estimated that production of each tonne of gold from non-refractory ore used approximately 200,000 gigajoules (GJ) of energy and 260,000 tonnes of water. It produced 18,000 tonnes of GHGs,,,
