The raw ore had an Au grade of 5.75g/t, a true density of 2.62t/m3 and a bulk density of 1.32t/m3, with gold being the major valuable mineral. ...
The Malaysia 700t/d gold mineral processing plant was a symbol of Chine-Malaysia cooperation in the mining industry under the policy of “The Belt and Road”. The raw ore consisted of pyrite, quartz, calcite and mica, with gold being the valuable mineral. It had a gold grade of 4.70g/t, silver grade of 4.63g/t, iron grade of 20.10% and a sulfur grade of 20.55%. ...
The Guinea 6,000t/d gold mineral processing plant was an EPC+M+O project. The design scope covered construction drawings and workshop drawings and involved engineers in the fields of mineral processing, water supply, and drainage, power, civil engineering, and general layout. ...
Although the traditional wet tailings pond has low cost and mature technology, it occupies a large area and seriously pollutes the surrounding environment. If a dam bursts, it may even endanger the lives of humans and animals. Dry tailings stacking can largely avoid such disasters. In addition, dry tailings discharge has the following significant advantages, which we will discuss together....
Zinc powder displacement of gold is a method of extracting gold. Its processing object is gold-containing precious liquid. Its working principle is to use zinc powder as a reducing agent to displace gold from the precious liquid. In the order of metal activity, zinc (Zn) is more easily oxidized than gold (Au). Therefore, in an acidic environment, zinc can reduce gold ions to metallic gold, and zinc is oxidized to zinc ions....
