machine. Specific chemicals are added to either float ( off) specific minerals or to depress the flotation of other minerals. Several stages of processing are generally involved with rough bulk flotation products being subjected to additional flotation steps to increase product purity. The flotation process in general does not float free gold particles but is particularly effective when ...

Roasting. It is a process that is applicable for sulphide ore which subjects to the heat and air. In roasting, the sulphide ore is heated at the temperature below the melting point. For example: Leaching. It is a chemical method in which the ore is treated with the suitable reagent to solubilize the ore.

To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don't want to melt them. As previously noted, materials that have been crushed to small sizes reacts better with the oxygen in the air. Don't seal up the material, as it needs to have access to air for the oxygen to react with the sulfur. Even if you get everything right and you're successful ...

ROASTING Roasting is generally applied to sulphide minerals and refractory ores. It involves a thermal gassolid reaction during which sulphides and sometimes organic carbon are oxidised to SO 2 and carbon dioxide (CO 2) at temperatures between 500ºC and 700°C.
