1.1 Chemical composition

Copper and iron are the two main elements in the raw ore, and exist in the forms of alpha chalcocite, covelline, enargite, iron pyrite. The gangue minerals are mainly quartz, dickite, alunite, and a small amount of iron oxide, etc. Gold symbiosis with other minerals closely, that is the raw ore is multi metal gold bearing refractory ore.

1.2 Mineralogical analysis

Based on the analysis of the occurrence state and distribution of gold in the overflow ore, it is found that a large part of the gold is dissociated from the raw ore, the visible gold in the overflow ore accounts for 36%. It can be seen from the distribution of gold in the ore that improving the recovery of visible gold is the key to increase the recovery rate. Taking enrichment and gold mineral scanning processes for the part of overflow ore, obtain 80 gold minerals. According to the count o...

The ore sample is a low grade gold bearing refractory copper ore, in which, gold is closely associated with copper sulfur minerals, the gold are distributed in the gaps. After the ore was dissociated, a large part of gold became granular gold, and it was difficult to achieve effective recovery by flotation, so the Knelson is used to pre recover the granular gold.

Using Nielsen concentrator which obtains synthetic recovery of 0.6+0.038 mmgold. Nielsen concentrator, the pre recovery of most of the particles of gold, can reduce the loss of gold in flotation operations, achieving the goal of the income received early.
