Carbonate

carbonate rocks The main minerals are hemimorphite smithsonite hydrozincite cerussite Fe-oxyhydroxides (including goethite) and hematite The deposits are broadly divided into three subtypes the more common – 1) direct replacement and 2) wallrock replacement and the less common – 3) residual and karst-fill Direct+ + o + o + = 14 Conversion of ore into oxide It is easier to reduce oxide than sulphide or carbonate ore Therefore the given ore should be converted into oxide by suitable method Roasting Calcination It is a process in which ore is heated in a regular supply of air at a temperature below melting point of the metal so as to convert the given ore into oxide It is a process of heating ore in

Skorpion zinc non oxide sulphide genesis

The Skorpion process was developed to treat a complex non-sulphide oxide ore body using atmospheric leaching followed by solvent extraction and electrowinning of zinc (1 2 3) Sauconite is the largest contributor to the zinc grade with lesser amounts of zinc hydroxides

Carbonate And Sulphide Ores Are Converted Into O Ide Ores How

  1. Flotation Reagents

    The most widely used sulphidizer is sodium sulphide which is commonly used in the flotation of lead carbonate ores and also slightly tarnished sulphides such as pyrite and galena In the sulphidization of ores containing precious metals careful control must be exercised as in some instances sodium sulphide has been known to have a depressing effect on flotation of metallics

Difference Between Roasting and Calcination

Jan 02 2018Although the final outcome of roasting and calcination is the same they are two different processes used to obtain metals from metal ores The final outcome of the two processes is the conversion of an ore into an oxide ore Roasting is the process of heating the ore in the presence of air

Why the Extraction of Copper from Chalcopyrite is so

About 3/4 th of Copper (Cu) produced in the world has come from Chalcopyrite (CuFeS 2) but it is the lowest standard ore of Copper The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate carbonate or sulphate ores

Conversion of Ore into Metal Oxide

Calcination Carbonate ores are heated in absence of air The absence of air and heat converts the CO 3 into CO 2 and O The O remains with the metal as metal – oxide Heating also expels any water content in the ore In case there are any volatile impurities or gases trapped in the ore they are also removed by heating
