Conversion method of copper chloride

Номер: CN116002746A
Автор: TAO JINFENG
Принадлежит:

According to the conversion method of the copper chloride, CaCO3 is adopted for converting CuCl2 into a chemical substance of bivalent copper, then FeCl2 is adopted for chlorinating the chemical substance of bivalent copper into CuCl and CuCl2, CuCl2 obtained through chlorination is recycled, the CaCO3 and FeCl2 are adopted for converting CuCl2 into CuCl, the raw material cost for converting CuCl2 into CuCl is effectively reduced, and the economical efficiency of the method is improved.

CuCl solution production method

Номер: CN115974131A
Автор: TAO JINFENG
Принадлежит:

The invention provides a production method of a CuCl solution, which comprises the following steps of: reducing a bivalent copper compound into CuCl in the solution by using an iron-based reducing agent, removing residual FeCl2 by using an alkaline substance, generating Cu, extracting a clean CuCl solution as output, and directly or indirectly reducing the bivalent copper compound by using the obtained Cu; according to the method, the iron-based reducing agent is adopted for converting CuCl2 into CuCl, the raw material cost for converting CuCl2 into CuCl is effectively reduced, meanwhile, the alkaline matter is adopted for removing residual FeCl2 so that the clean CuCl solution can be produced, and therefore the problem that the raw material cost for producing the clean CuCl solution is high is solved.

Conversion method of calcium compound

Номер: CN116575108A
Автор: TAO JINFENG
Принадлежит:

The invention provides a conversion method of a calcium compound, which comprises the following steps: reacting calcium halide/calcium nitrate with sulfate in a solution to generate calcium sulfate whisker and metal halide/metal nitrate, preferably reacting calcium halide with sulfate in the solution to generate calcium sulfate whisker and metal halide; the salt-containing solution produced by the method is easy to treat subsequently.
