（ Cover: zhengzhou DE source extraction China non-ferrous metals metallurgy of the fifth conference)
China non-ferrous metals metallurgy of the fifth conference on October 24-2018 26 in jiangxi province � � city jinjiang international hotel, zhengzhou DE source extraction technology co. , LTD. , as China nonferrous metals industry technology innovation strategic alliance, deputy director of the unit, was invited to the meeting, and get. cwl - M series, environmental protection new centrifugal extraction equipment at the scene.
it is understood that to promote the progress of science and technology and green development, non-ferrous metal industry in China zhengzhou DE source extraction over the years committed to non-ferrous metal wet extraction technology and equipment research and application of its. cwl - M series centrifugal extraction machine not only high extraction efficiency, strong corrosion resistance, low power consumption, and free maintenance, high degree of automation, operation environment is good, has the absolute advantage in the field of non-ferrous hydrometallurgy.
a, nickel and cobalt separation extraction
due to the chemical properties of cobalt and nickel are very similar, paragenetic and associated in deposit and therefore in various cobalt waste residue containing nickel. In a variety of special alloy materials, battery materials, catalysts, are all at the same time containing cobalt and nickel. So in the recycling of cobalt, cobalt nickel separation is the most important.
cobalt, nickel separation are mainly chemical precipitation method and the method of solvent extraction, the solvent extraction method with high selectivity, high recovery rate, simple process, continuous operation, and the advantages of easy to realize automation, have become the main method of separation of cobalt and nickel. And the use of new. cwl efficient centrifugal extraction machine, and further accelerate the process of the development of the extraction separation of nickel and cobalt.

2, vanadium extraction and separation of
vanadium leaching liquid with low pH, high content of impurity ions is much and etc. So, vanadium leaching liquid purification of enrichment is critical. Enrichment of vanadium from the acidic leaching liquid, extraction method is more suitable for, USES the extraction can make low concentration enrichment of vanadium pentoxide get ( From several enrichment to g/L g/L) , thus to sink vanadium and vanadium in the leaching liquid and the vast majority of impurity separation and purification steps instead. Among them, the. cwl - M high efficient centrifugal extraction machine become vanadium leaching liquid concentration at the core of the extraction equipment.

3, rare earth extraction separation
our powers are rare resources, such as tungsten, titanium, rare earth, gallium, uranium, molybdenum, thallium, vanadium, zirconium, tantalum, niobium, lithium, beryllium, etc. , not only complete kinds, and reserves also is very rich. But with the expansion of the rare earth industry, rare earth resources recycling process of 'three wastes' pollution problems become increasingly serious, be badly in need of development of efficient utility of green mining mineral smelting and processing, solve the problem of three wastes pollution to the environment, and to further reduce product consumption and improve the comprehensive utilization of resources.
Beijing nonferrous metal research institute and professor YouYan rare earth new materials co. , LTD. Xiao-wei huang, lead the team system was carried out by rare earth separation green chemistry basic theoretical research, proposed to the ionic rare earth mine instead of alkali metal or alkaline earth metal calcium magnesium ammonium, unbalanced centrifugal extraction instead of precipitation recycling and purification of enrichment of rare earth and other new ideas, invented the new technology of extraction and separation of ionic type rare-earth ore efficient green, from the source to reduce ammonia nitrogen, radionuclide pollution, water and material efficient recycling, is a new kind of clean production technology.
