Gold processing
Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

Placer Gold Mining
The gold dredging is mostly done by small-scale miners using suction gold dredges. These are small machines that float on the water and are usually operated by one or two people. A gold dredge consists of a sluice box supported by pontoons, attached to a suction hose which is controlled by a miner working beneath the water.

What You Need To Know About Mineral Processing
In simple terms, mineral processing is separating commercially valuable minerals or metals from other rocks. It's not often that you dig up a large gold nugget. Instead, small particles of gold can be found mixed in with other minerals, metals, and rocks, some valuable, and some not. The collection of all these materials together is called ore.

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