WebThe conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, ... which is called matte or copper matte. The term matte grade is normally used to refer to the copper content of the matte. WebSolution. The correct option is C Copper sulphide and ferrous sulphide. In the metallurgy of copper, the ore is heated in a reverberatory furnace after mixing with silica. In the furnace, iron oxide ‘slags of’ as iron silicate and copper is produced in the form of copper matte. Copper matte thus formed consists of copper sulphide and ...
WebCopper slag is a by-product of copper extraction by smelting. During smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or … WebCopper matte consist of : (1) Copper oxide and ferrous sulphide (2) Copper sulphide and ferrous oxide (3) Copper sulphide and ferrous sulphide (4) Copper oxide and ferrous oxide 62.

WebFeb 21, 2024 · Matte consists of base metal sulphides (cobalt, copper, iron and nickel). Matte serves as a collector for the PGMs [6, 7, 14]. Operating temperature of matte and slag varies with the composition of the concentrate . Typical smelter operating temperature for matte varies from 1380 to 1600°C, and that of slag varies from 1500 to 1680°C .
The roasting process is generally undertaken in combination with reverberatory furnaces. In the roaster, the copper concentrate is partially oxidised to produce "calcine". Sulfur dioxide is liberated. The stoichiometry of the reaction is: CuFeS2 + 3 O2 → 2 FeO + 2 CuS + 2 SO2 Roasting generally leaves more sulfur in the calcined product (15% in the cas… form 8 mental health albertaWebMay 7, 2024 · The pyrometallurgical copper-making process consists of four steps in which the concentrate of polymetallic sulfides is refined into copper. These four steps are[2,3,4,5]: Smelting This is a continuous oxidative-smelting process that produces two immiscible liquids: slag and copper matte. form 8 mental healthWebCopper matte is obtained by fusion of roasted copper sulphide concentrates or ores to separate the copper sulphide from the gangue and other metals which form a slag that floats on the surface of the melt.
