The iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Xinhai use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings.

03/11/2020· The carrier minerals of gold, silver-gold deposits, are all related to pyrite, and most of them are dominated by the inclusion of pyrite. It can also be seen that it exists in a co-existence with pyrite. The grain size of silver-gold ore is generally between 0.02 and 0.12 mm, which is relatively coarse.

22.08.2014· Mining reports will often mention if gold veins occur in the quartz. Another thing worth noting about the quartz is that the kind of quartz that gold is generally found in is not pure white. Most commonly it will show significant iron staining, and the quartz will have a dirty appearance with reddish/brown stains.

The now extinct Us Bureau of Mines conducted numerous studies of gold in pyrite, and sulfide ores over the years, until their untimely demise in the 1990's. Much of the referenced studies and case applications discussed in this brief article came from USMB reports, which even after they ceased to exist, still continue to provide some good scientific information to those working in the mining

Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling cracks and openings in the vein material. The gold can be such small particles as to be invisible to the naked eye, or as larger aggregates of easy to see blobs, leaves and crystals in cavities in the quartz. The gold fills cracks and spaces in the

Gravity concentration tends to recover the pyrite with the gold, and only removes the lighter minerals, such as quartz, from the ore. The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current
