Abstract

In this work the production of Copper sulphate (II) Sulphate CuSO4 important industrially and that of creating (100 L) a solution of Copper (II) nitrate, Cu(NO3)2, underdeveloped gold filter and isolate the silver from jewellers operations in drums which not throw it as manure in the river up to (130_ 1470 kg) which is a very large quantities as well as to the presence of lead nitrate pb(NO3)2 toxic that does not separate during silver separate also thrown in sewers and rivers, sometimes may contain ions, zinc, Nickel, Lead by raw user while Silver isolate job goldsmiths process as the process of adding sulphuric acid as possible to be recycled and recovered any of this enters into the economic side in the copper recovery process after any purification of copper sulphate crystal blue restart with both sides of the production of nitric acid and copper sulphate process.
