渣浆泵加温氧化抑制方法

使用氧化剂作为抑制剂存在的主要问题是:当矿中还原性物质很多时，其耗量大，不经济，因此加温搅拌抑制方法应运而生。该法可不用氧化制，矿浆温度为40- 50C碳酸钠调浆至pH为7~9并加以搅拌。某高硫高砷含金黄铁矿，原矿金品位为10g/t。砷以毒砂形式存在，品位为4.79%，硫和铁含量分别为33. 73%和47.3%，经细磨的矿浆加温至45C，搅拌0.5h,用丁黄药150g/t和2号油25g/t进行硫砷分选，经一粗三精，获得金硫混合精矿，其中砷为0.45%，硫为47.35%， 金为23.05g/t， 砷脱除率为97.2%金硫混合精矿用石灰抑制黄铁矿浮金，浮选金硫后尾矿主要是磁黄铁矿和毒砂，弱磁选得合格磁硫铁矿精矿，磁选尾矿中的毒砂经硫酸铜活化，黄药捕收得金砷精矿。渣浆泵厂家
    需要指出的是:在采用上述三种氧化抑制方法的过程中，不仅要控制氧化剂的浓度，而且要控制好氧化时间、搅拌强度、搅拌时间以及矿浆温度等，否则不仅达不到理想的分选效果，而且还会恶化浮选过程。例如，搅拌时间的长短，不仅使矿物表面性质发生变化而影响其可浮性，而且还影响矿浆中的离子组成，而溶液中的离子组成对矿物的分选起着很大的作用，所以需要调整好搅拌时间，调节好矿浆中的离子组成，使之有利于

The method of heating and oxidation inhibition of slurry pump

The main problem of using oxidant as inhibitor is: when there are many reducing substances in the ore, its consumption is large and uneconomical, so the method of heating and stirring inhibition came into being. This method does not need to be oxidized. The pulp temperature is 40-50c sodium carbonate, the pulp is adjusted to pH 7-9 and stirred. A high sulfur and high arsenic gold bearing pyrite with a gold grade of 10G / T. Arsenic exists in the form of arsenopyrite, with a grade of 4.79%, sulfur and iron contents of 33.73% and 47.3% respectively. The finely ground pulp is heated to 45C, stirred for 0.5h, and then separated with 150g / T of butyl xanthate and 25g / T of No.2 oil. After one roughing and three refining, a mixed concentrate of gold and sulfur is obtained, in which arsenic is 0.45%, sulfur is 47.35%, gold is 23.05g/t, and arsenic removal rate is 97.2%. The mixed concentrate of gold and sulfur suppresses pyrite flotation with lime The tailings after flotation of gold and sulfur are mainly pyrrhotite and arsenopyrite. Qualified magnetite concentrate is obtained by weak magnetic separation. Arsenopyrite in magnetic separation tailings is activated by copper sulfate, and gold arsenic concentrate is obtained by xanthate collection. Slurry pump manufacturer

It should be pointed out that in the process of adopting the above three kinds of oxidation inhibition methods, not only the concentration of oxidant, but also the oxidation time, stirring intensity, stirring time and pulp temperature should be controlled, otherwise not only the ideal separation effect can not be achieved, but also the flotation process can be deteriorated. For example, the length of mixing time not only changes the surface properties of minerals and affects their floatability, but also affects the ion composition in the pulp. The ion composition in the solution plays a great role in the separation of minerals, so it is necessary to adjust the mixing time, adjust the ion composition in the pulp and make it beneficial to the flotation
