Use of Quartz-Containing Materials as Fluxes in

2017-5-20  Under pyrometallurgical process conditions for copper preparation carried out at atmospheric pressure in the range 20–1350°C of greatest importance are the following quartz transitions: from α- to β-condition at 573°C, accompanied by an increase in specific volume by 4.94%, and β-quartz into β-cristobalite [6, 8] at 1050–1130°C (increase in specific volume by 18.9% with respect to α-quartz). In view of this, of particular importance for production processes

Copper Smelting - an overview ScienceDirect Topics

Production of copper by leaching/solvent extraction/electrowinning increased markedly in the last two decades of the twentieth century. It is only limited by the availability of leachable “oxide” and supergene sulfide ores. So far, industrial leaching of hypogene copper (e.g., CuFeS 2) ores has not yet proved to be feasible. It is, however, the subject of considerable ongoing research.

Combined Processing of Copper-Smelting Slags for

2020-1-14  We developed a simple and effective process of production of proppants from slags. A charge for proppants is a mixture of a slag (about 50%), quartzite, and Al 2 O 3-cotnaining wastes. The technological process includes melting of a slag with additions, centrifugal spraying into granules of a give size, heat treatment, and separation.
