天然碱代替纯碱的磷矿选矿试验

经过煅烧的天然碱可以在浮选作业中代替纯碱使用。王集磷矿一、三层混合矿和宁夏贺兰山磷矿使用这种煅烧天然碱,浮选指标均优于原使用纯碱的工艺。该药剂来源广,价格低,可以为企业带来较大的经济效益。

Phosphate processing test with trona in place of soda ash

The calcined trona can replace soda ash for use in the flotation operation. The phosphate ores from a combination of the first and third beds of Wangji phosphate deposit and from Hclanshan Phosphate Mine are flatated using the calcined trona with the resultant indexes better than that with soda ash. This reagent with extensive source and lower cost can bring about substantial economic benefits for concentrators.
