According to the classification of their chemical composition, the iron ore can be divided into magnetite, hematite, limonite and siderite. According to the specific magnetization coefficient, the iron ores can be divided into strong magnetic minerals and weak magnetic minerals.
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.
There are rare native copper deposits but abundant copper tailings in China. According to incomplete statistics, hundreds of millions of tons of copper tailings are discharged every year in China, which are increasing year by year. Copper tailings include little copper, silver, zinc, lead ore, but a large number of silica-aluminate tailings, such as calcite, […]
Protecting water resources, preventing water pollution and improving water environment ecology are important parts of environmental protection and sustainable development.
Most non – ferrous metals are metal sulfides ores, such as lead-zinc ore, copper sulfide, which often coexist with a large number of pyrites. Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in lead-zinc tailings recovery.
Copper ore refers to the mineral aggregate with a certain content of copper ore and can be recycled at the present stage. In general, copper ore is occurred in ore inside as sulfide, and associated with a certain amount of lead and zinc ore.
The common copper sulfide minerals mainly include chalcocite, covellite, bornite, copper pyrites and tennantite, and their inherent floatability decrease in turn. Copper sulfide ore has better floatability than sphalerite, pyrite and other sulphide, so it is more likely to float from the pulp by adsorpting collecting agent.
