ENRICHMENT OF GOLD ORES BY GRAVITY METHOD

Abstrak

This article is about extracting gold, one of the rare metals. Rare metals are distinguished by their higher density than other metals and the minerals that come with it are also denser. That's it in the separation of rare metals in the natural state due to the gravity method enrichment is effective. Many gold-bearing ores are known amount of pure gold (+1) mm, not only poorly separated in flotation, but it is poorly separated in hydrometallurgy, for this reason ores Enriched by the initial gravity method, the large ones are separated prevents waste and is ready for faster sale the product is received. In modern practice, the following main machines are used in gravity beneficiation to extract gold from ores of root deposits: sedimentation machines, sluices, concentration table, drum concentrators, short cone hydrocyclones.
