Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.

Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at

Effective costs of Copper Processing As each tonne of ore produces 0.0051 t of copper in concentrates, with a free market value of £ 5.00, so total production costs of copper in concentrates : However, if the ore contains appreciable by-products, the effective production costs are reduced. Assuming the concentrate contains 25 gpt of gold and

During smelting, copper will be extracted from the malachite ore. The efficiency of our smelting process will be determined by calculating the copper yield: the percent of copper in the ore that was extracted by the smelt. Before coming to class, calculate the amount of copper in each crucible charge.

The Egyptian copper smelting process utilized a ’bowl furnace’ which was supplied additional air, to raise the temperature of the fire, through the usage of foot bellows. Malachite and azurite were used as a source ore for the copper, charcoal was used as the reducing agent to separate oxygen from the copper, and iron ore was used as the

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper Bearing Ore. There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.

Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the copper-containing minerals.

Sulfide and Oxide Copper Ores. Nearly all copper ores of the sulfide type such as chalcocite, chalcopyrite, and covellite are treated through the well-known process of smelting. After the ore is crushed to powder, it is treated with froth flotation, whereby the powder reacts with reagents that treat the copper to make it hydrophobic.
