Copper: smelting, producing and classification

There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical. Nowadays, the main smelting method is pyrometallurgy, which accounts for 85% of output in the world. The details are as follows: A. Pyrometallurgy; Pyrometallurgy usually adopts original ore, in which its content can reach 20%-30% after mineral processing.

Extractive_metallurgy - chemeurope.com

Extractive metallurgy is the practice of extracting metal from ore, purifying it, and recycling it.. Most metals found in the Earth's crust exist as oxide and sulfide minerals.These compounds must be reduced to liberate the desired metal. There are two methods of reduction: electrolytic and chemical.. Chemical reduction can be carried out in a variety of processes, including reductive smelting

Dissolution and reduction of chromite ore - Pyrometallurgy

chromite ore was fed into the molten slag, and was followed by reduction of iron and chromium oxides. Due to the fact that the chromite ore was fed in granular form, as expected, a greater contact area was created which influenced the dissolution / reduction reaction between the ore and the slag. The slag composition played a significant role

12.3 Primary Copper Smelting

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to

Pyrometallurgical Process - an overview |

Depending on the ore from which nickel is obtained, some of the slags produced can also be enriched in other metals such as copper, which may also be extracted as a valuable commodity. Kalinkin et al. 76 produced alkali-activated binders based on Cu–Ni slags from such a process, and found that grinding of the slags increased their reactivity, particularly when a CO 2 atmosphere was imposed
