How to Process Gold Ore? 4 Gold Processing Steps

Gold flotation process is suitable for processing gold bearing sulfide ore with fine particle size and good floatability. During flotation, sulfide ore is enriched into sulfide concentrate as a carrier for gold. Flotation can also be used to process polymetallic gold-bearing sulfide ores and carbonaceous ores. Gold flotation machines:

Mineral Processing

Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
