Method for preparing copper sulfate from copper concentrate

According to the website of Jinchuan Group, the present invention discloses a method for preparing copper sulfate from copper concentrate. The method is to add compounding additives to the copper concentrate powder so that the iron in the copper concentrate is precipitated in the roasting process with the basic iron sulfate which forms insoluble sulfuric acid solution, and the copper roasting sand is In the case of copper sulphate, the residue is filtered out with the residue, the filtrate can be cooled without crystallization by direct removal of iron, and filtered to obtain a qualified product of copper sulphate. The filtrate is supplemented with sulphuric acid and water to adjust the density and returned to the leaching stage. The leachate is recycled. The invention overcomes the defects of complex iron removal and purification operation of the sulfuric acid method and high copper consumption, the utilization ratio of the raw material copper can reach over 96%, the process flow is short, the operation is simple, the energy consumption is low, the mother liquor is fully recycled, and the industrialization is easy to implement.

Electroplated Diamond Abrasive Products

Superabrasives are tools used in precision grinding,precision cutting,precision polishing and precision drilling,like flexible diamond abrasive.Superabrasive materials attach to a wheel,blade and drill to make Superabrasive grinding wheels,cutting balde and drilling bit.The reason some abrasives are Superabrasives is due to their extraordinary hardness,unparalleled performance,and longevity.
What are Superabrasives?
Abrasives that belong to the Superabrasive family includes,Industrial diamonds: an industrial diamond is a non-gem quality small diamond that is for abrasives,cutting,and drilling tools.
Cubic boron nitride (CBN): Usually called CBN it is the second hardest cutting tool material after a diamond.
Polycrystalline: Is an abrasive material that has a multiple collection of crystal grain structures with individual orientations
CVD Diamond: These are synthetic diamonds made by a process known as chemical vapor deposition.CVD diamonds grow from a hydrocarbon gas mixture. They are extremely hard,have a high thermal conductivity that is five times that of copper. They also have broadband optical transparency,are chemically inert,and only reach graphitization at very high temperatures.
Nanodiamonds: These tiny diamonds are the product of a controlled explosion. Sometimes called a detonation nanodiamond (DND) or an ultradispersed diamond,as this is how they form.
Industries That Use Superabrasives

Advantages of Superabrasives
The advantages of Superabrasive grinding wheels are more than extraordinary hardness,unparalleled performance,and longevity. These three features of Superabrasives are the core of many advantages manufacturers gain by an aggregation of services that normal abrasives simply cannot deliver.
These include:
Less expensive tooling and fixturing costs
More wheels on the spindle,smaller wheels,multiple operations
Less floor space needed for manufacturing
Virtual elimination of wheel wear
Automated CNC machines,less labor intensive operations requiring less training
Consistent surface speed from part to part
Better overall throughput with fewer machines needed
Improved Material Removal Rates,Lower Per Part Abrasive Costs and higher speeds
With Superabrasives,production increased by automated CNC equipment,industries have found one way to compensate for the lack of availability of skilled labor. With fewer machines needed,so is fewer workers. With Superabrasives CNC,automation is more concerned with defining a manufacturing process using machine capabilities and mechanization. There is less concern on operator technique. A properly defined process,combined with automatic loaders make for equipment that is almost running itself.
Industry Outlook
Future growth of the abrasives industries will primarily be in Superabrasives. Currently,research and development of Superabrasives are taking place in the following areas.
Custom designed [hard to grind" materials in an increasing number of industries
Creep or deep feed grinding
High-speed,high-performance grinding of hardened steel
Form grinding,sometimes with electroplating,in high precision,high-removal,and high-surface quality applications
CNC-control of line grinding machines
Other abrasive technology developments with Superabrasives are likely to occur in using CVD for the best bonding of coatings to diamond wheels
