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. ...
Skarn iron ore is a type of iron ore deposit related to contact metamorphism of intermediate-acidic intrusive rock bodies. The ore minerals of this type of iron ore deposit are mainly magnetite, and hematite, siderite, specularite, etc. can be seen. The gangue minerals are skarn mineral combinations, such as garnet, diopside and hematite. Skarn iron ore is an important iron ore resource. The selection of mineral processing procedures and equipment is an important link to improve the quality of iron concentrate. This article introduces the main mineral processing procedures and key equipment....
After fluorite is extracted through mineral processing, the tailings are usually discharged and stored in a tailings pond. In fact, fluorite tailings still have great utilization value. For example, the quartz in them can be further extracted. Quartz is widely used in metallurgy, building materials, electronics and other industries, especially high-purity quartz, which has higher utilization value in coatings, optics, and precision materials. Therefore, the significance of extracting quartz from fluorite tailings is not only to obtain surplus value, but also to avoid waste of resources and make the best use of them. So, let's discuss the operation method of extracting quartz from fluorite tailings....
