Nowadays, easy-to-separation gold ore resources are decreasing. The hard-to-separation gold ores become the object of development and research. The below takes a kind of hard-to-separation gold ore as an example to introduce the gold beneficiation process and equipment which are needed in ore beneficiation plant.

In the ore grinding process, it is often necessary to achieve the separation of different minerals through selective grinding, prevent the overgrinding of valuable minerals to be received, and reduce the over crushing of gangue minerals. In the ore milling process, there are many factors affecting the selective grinding effect, such as ore properties, mill machine type, operating conditions, etc. In this paper, we will explore the factors affecting selective grinding from these three aspects.

In the flotation process, the flotation separation effect of the target mineral is affected by many factors. This paper mainly introduces the influence of pulp concentration, flotation particle size and flotation machine speed on the flotation efficiency of chalcopyrite copper ore and pyrite.

In this paper, fine scale graphite and cryptocrystalline graphite are selected as representatives to discuss the difference in graphite ore beneficiation process from four aspects of grinding method, grinding concentration, medium ore return mode and pharmaceutical dosage.

This article will introduce you to a purification process of high-purity quartz sand, that is, the magnetic-flotation-acid leaching separation process of quartz sand.

The main methods used in lithium ore separation include flotation, magnetic separation, heavy medium, combined dressing, among which flotation is one of the widely used beneficiation methods.

With the increasing popularization of the concept of carbon neutrality and new energy technologies, more and more attention has been paid to the development and utilization of cobalt mineral resources. In nature, most cobalt minerals are symbiotic with iron, copper, nickel and other metal minerals, and a single cobalt mineral is relatively rare.

In the beneficiation of quartz mineral, the separation of different mineral components and quartz is an important issue, which has a great influence on the purity of quartz concentrate. Mineral components commonly found in quartz mineral include mica, feldspar, iron-bearing minerals, and apatite. In this article we describe how the common mineral components in quartz mineral are separated.

Because of the different types of lithium-rich ore, the mineral processing process used is also different. The following will introduce three lithium-rich mineral lithium extraction processes, spodumene, lithium micite and lithium phosphate ite.

At present, there are more than 50 kinds of nickel ore resources, but the nickel resources that can be developed are mainly nickel sulfide and nickel oxide. The following editor will sort out the characteristics of these two nickel minerals and the suitable beneficiation process for you.

Graphite ore is often associated with quartz, illite, kaolinite, sericite and a small amount of hemite, limonite, calcium carbide, calcite, etc., which need to be purified and applied. There are six common graphite extraction processes: selective flocculation, flotation, basic acid, acid leaching, chlorination and high temperature roasting.

At present, the common methods for extracting lithium from lepidolite are mainly lime roasting, sulfuric acid roasting, sulfate roasting, chlorination roasting and pressure cooking. Let's understand the characteristics and advantages and disadvantages of these mica lithium extraction process methods.
