一、绪言目前高冰鎳处理方法有:(1)分层熔炼法;(2)水冶法;(3)羧基法;(4)低銅高鎳直接电解法;(5)浮选法。本文針对浮选法加以論述。它比分层熔炼法有很多优点。如改善劳动条件,提高分离指标,降低生产成本(处理一吨高冰鎳成本可以降低三倍);比其他方法減少大量的原材料消耗,如燃料、熔剂、电能和鎳粉等,以及避免使用高压密封設备。用浮选法处理高冰鎳是近二十年来才发展起来的。加拿大于1944年首先在Copper—Cliff以該方法
I. INTRODUCTION At present, the treatment methods of high iced nickel include: (1) stratified melting method; (2) hydrometallurgical method; (3) carboxyl method; (4) low copper high nickel direct electrolysis method; This article discusses the flotation method. It has many advantages over stratified melting. Such as improving working conditions, improving separation indicators and reducing production costs (three times the cost of handling one tonne of iced nickel); reducing the use of large amounts of raw materials such as fuels, fluxes, power and nickel than other methods and avoiding the use of high pressure Sealing equipment. The flotation method has been developed for nearly two decades. Canada first used this method at Copper-Cliff in 1944
