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 treated by smelting.

are easier to process, through conventional mining, smelting and refining, compared to laterite ores which require intensive hydrometallurgical processing (such as high pressure acid leaching or HPAL). This means that laterite ores typically require substantially more energy and chemicals to produce than sulfide nickel.

Cobalt extraction - Wikipedia

Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions.

Extractive Metallurgy of Nickel, Cobalt and Platinum Group ...

Two different nickel sulfide intermediates must be refined to pure nickel and cobalt products: sulfide matte from nickel sulfide smelting and converting and sulfide precipitates from nickel laterite leaching. These data indicate that hydrometallurgy is the principal method for making high-purity nickel from these mattes and sulfide intermediates.

Summary. Factors which influence the economics of smelting processes for copper, nickel, zinc, and lead include metal prices, cost of finance, the rate at which investment capital can be recovered, possibilities for retrofit, grade and complexity of the concentrates, location, the cost of energy and process energy efficiency, cost of pollution control, and the profitably of by-product sales.

12.3 Primary Copper Smelting

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.
