氧化铜矿硫化强化浮选研究与应用分析
|
摘要
通过孔雀石和硅孔雀石的单矿物和实际矿石浮选试验,研究了硫化钠对不同粒级孔雀石和硅孔雀石浮选的影响,矿浆pH值、硫化时间、浮选机转速对+53μm粗粒级孔雀石浮选的影响,以及强化活化剂乙二胺膦酸盐对不同粒级孔雀石和硅孔雀石浮选行为的影响。利用红外光谱分析和氧化铜表面溶解行为测试,分析了氧化铜矿表面强化活化剂的作用机理,为实际矿石浮选提供的了技术依据,提高了实际矿石浮选技术指标,回收率提高2. 03个百分点。
In the single mineral and actual ore flotation tests of malachite and chrysocolla,the effects of sodium sulfide and the intensified activator ethylenediamine phosphonate on the flotation of malachite and chrysocolla with different grain grade were studied separately; the effects of pulp pH value,vulcanization time and revolution of flotation machine on the flotation of malachite with coarse grain + 53 μm were studied also. Using the infrared spectrum analysis and the test of the surface dissolution behavior of copper oxide,the mechanism of the intensified activator on the surface of copper oxide ore is analyzed. And then,the technical basis is provided for the actual ore flotation. The technical index of the actual ore flotation is improved,and the recovery rate is increased by 2. 03 percent points.
