浮选金精矿氰化前碱预处理，使氰化钠耗量由６ｋｇ／ｔ降至３１ｋｇ／ｔ。氰化浸出前加碳质物的纯化剂煤油２～４ｋｇ／ｔ，金的浸出率由９２５１％增至９３１７％。含铜金精矿用氨氰化处理，铜的浸出率由２９４１％降至２３５１％，氰化钠耗量由４５ｋｇ／ｔ降至４２５ｋｇ／ｔ。金精矿细磨氰化工艺中，采用适宜的搅拌强度，可以减少碱及氰化物的耗量。 Flotation of gold concentrate pre-cyanide pretreatment of sodium cyanide consumption decreased from 6kg / t to 3  1kg / t. The kerosene, which is the purifier of carbonaceous material before cyanidation leaching, is 2 ~ 4kg / t, the leaching rate of gold increases from 9251% to 9317%. Copper-bearing gold concentrate was treated with ammonia cyanidation, the leaching rate of copper dropped from 2941% to 2351%, and the consumption of sodium cyanide dropped from 45kg / t to 425kg / t. Fine gold refining gold cyanide process, the use of appropriate mixing strength, can reduce the consumption of alkali and cyanide.
