Therefore, the tailings reprocessing technology not only greatly reduces the tailings storage and utilization rate, but also brings considerable economic benefits.

Ordinarily, fluorite mineral is suitable for gravity separation and flotation separation. Xinhai thinks that jig could be used in the gravity separation for the crude Fluorite mineral lump ore.

According to the existence form of molybdenum mineral, molybdenum mineral processing technology can be divided into single molybdenum mineral processing technology and copper-molybdenum mineral processing technology.

In recent years, China has been advocating circular economy and sustainable development, especially in the recycling of mineral resources (mainly mine tailings). At present, the main problem is that many mineral processing plants do not have their mine design and research institutes, so they can't design the most reasonable tailings process.

It is known that hematite is the main raw material of the iron industry, its recycling has become the research focus. Here is the newest hematite processing technology—magnetic separation-anionic reverse flotation process.

Generally, low grade phosphate ore often contains high gangue minerals content in China, and the phosphate ores are closely associated with gangue minerals, so flotation process is the most effective separating method.

There are a variety of toxic heavy metal ions in lead-zinc tailings, these ions often exist in tailings as the solid form, but with the change of physicochemical properties.

Large discharging of lead-zinc tailings not only occupies land area, but also pollutes environment. Tailings will make a difference under the condition of stacking, such as oxidation, hydrolysis and weathering, which make pollution-free components transform into polluting components.

Copper ore usually refers to mineral aggregate in the nature that can be used to extract metal copper, generally copper sulfide and copper oxide. Copper minerals in nature mainly include pyrite, chalcopyrite, tetrahedrite, chalcocite, azurite, malachite, etc.

Flotation process is the common copper ore dressing method. This paper will introduce the copper flotation process of a copper ore dressing plant in Shanxi province.

China is a major nation of mining production and consumption in the world. Many provinces and cities possess high-quality lead-zinc mine in China, however, due to the unreasonable utilization, the large number of lead-zinc tailings are piled up for a long time, which takes up a lot of lands.
