New scientific technologies have been applied to refine the impure lithium pyroxene ore while an advanced production line has been established to get great promotion and development.
With new device and outstanding technique, the output of lithium hydroxide is about 300 tons. At the same time,reforming of the Jiangxi Lithium hFactory ,promotion of various grade of lithium carbonate quite meet consumers’neeed.
Floatation has wide used in refining impure cooper and helps the Huili Cooper Factory to gets economic approvement by the recycle of resource.
Chelation is an another good way to refine non-ferrous metal,especially on the bad weather condition with high altitude. The capacity of 2000 ton in Lunlang Lead-Zinc mine has prove it in effect.
The dangerous chemical liqulid and solid waste are transferred to general castoffs and high purity valuable metal to be brought out.by the hydrometallurgy technology .
With the factors of the development of the national economy ,increasing demand of non-ferrous metal and decreasing of the mineral resource, the constrict of technical condition make big wast and loss at each tache of materials using. For copper and nickle, there are thirty million to fifty million copper and nickle wast residues from electroplating, steel-making,petrifaction and electron industry, these wast residues are thought to be dangerous chemical wast, and they are always be coverd up, this makes loss of 150 thousand tons copper, 25 thousand tons nickle and many zinc,chrome and iron every year. Our nation expense 90 billion to 150 billion yuan to deal with these chemical wast every year, but they can’t avoid second pollute from heavy metal to water and soil.
Based on traditional acid leaching method ,our group made research and innovation, by using absolutely new acid leaching method. We can recycle not only Nickel, Copper, Zinc, but also chrome,iron, etc. in one process flow, we can produce several products such as Electrolitic Copper, Electrolitic Nickel, zinc inqot, chrome hydroxide,iron oxide etc. the recycling rate of Nickel, Copper, Zinc is more than 98%, 97%, 96%, more important is the new technology can invert the hazardous waste to normal waste, all industrial effluent is used in closed circulating system, ultimately achieve the goal of cleaner production, accord with the policy of National Enviromental Protection Industry.
By using this technic, the group established a series of comprehensive equipments, integrating recycling and producing, which can process more than 500,000 mts castoffs and produce 2000 mts electrolytic nickel, 2000 mts electrolytic copper, zinc ingot,chrome hydroxide,iron and some other products.It’s the one and only large-scale comprehensive recycling system that process copper and nickle castoffs, which are dangerous. It not only brings about 1-1.5 billion production value every year, but also retrenches about 6 billion environmental and recycling expense for our country. The system ,to a great extent, reduces secondary pollution to soil, river, ground water by these castoffs.
