The gold mine pool leaching process has strict requirements on the dosage of cyanide solution; too much is of a waste and (36) too little can't guarantee the leaching effect. When using CNFREE eco-friendly gold leaching reagent, the requirements can be appropriately relaxed (37) in terms of dosage,and the same leaching effect of cyanide can be obtained, which saves cost and reduces environmental pollution. Add a small (38) amount of leaching material to the ore, agitate it uniformly and (39) put it into the pool, then spray the leaching solution containing CNFREE gold environmental leaching solution with the spray system to prevent the solidification of gold ore in the pool, and greatly (40) improve the permeability and leaching rate of the gold mine.
