There is a long history to extract metal from ore directly with heap leaching process. This process is firstly used in low-grade copper deposits and then used in the leaching of low-grade uranium ore.

As the lead-zinc ore is related to the flotation, the following will focus on the simple introduction of the flotation cells.

At present, the graphite production process methods are mainly gravity, flotation, electric separation and the combination methods of the whole solutions.

For its ferromagnetism, magnetite can be separated by magnetic separation easily. However, magnetite is often associated with hematite and martite, so we often adopt combination process to get high-grade magnetite concentrate, such as gravity separation process, flotation process, etc.

Similar to other mineral processing solutions, there are many factors that affect the copper mining processing.

The common fluorite ore dressing processes include gravity separation and flotation process. Gravity separation process can be used for coarse-grained fluorite ore.

Iron ore reverse flotation method is invented in order to make a rational utilization of mineral resources. Here is a brief introduction of iron ore reverse flotation method.

According to the above calculation of mining and dressing costs, the unit overall cost of each gold mining and dressing is about 114.93 dollars per ton and the annual total costs is about 5,172,100 dollars

Generally, there are many influential factors in the gold flotation process, like particle size, flotation reagents, pulp density, the flotation time, stirring intensity, inflating volume, pulp temperature, and etc.

The project of Jinxin Molybdenum, located in Shuidi Town, Songshan District, Chifeng City, Inner Mongolia Province, China, is an Exploring & Processing mining joint enterprise with the capacity of 1000t/d, and is an EPC Project provided by Xinhai. This project started from June in 2005 to May in 2006, which spent 11 months.

Hematite is a kind of weak magnetic minerals, it is hard to get hematite concentrate by single magnetic separation process (including roasting magnetic separation and magnetic separation). Therefore, Xinhai often combine magnetic separation process with other hematite ore dressing processes rather than adopting single magnetic separation process
