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. ...
Molybdenum metal has the characteristics of high temperature resistance, high melting point, and high rigidity. Most of the molybdenum ores currently developed and utilized are molybdenite, which is recovered by flotation process. The embedded particle size of molybdenite is relatively fine, and it is often associated with minerals such as pyrite, chalcopyrite, and galena....
In the field of mineral processing, ball mills are indispensable grinding equipment, and their performance directly affects the efficiency and cost of the entire production line. The filling rate of the ball mill, that is, the volume ratio of the grinding media (such as steel balls and steel rods) inside the mill, is one of the key parameters affecting the grinding efficiency. This article will deeply explore the impact of the ball mill filling rate on the grinding efficiency, and provide a reference for enterprises to optimize the production process....
