过二硫酸钾的氧化抑制渣浆泵方法
    使用过二硫敢钾氧化抑制毒砂.比使用大量的石灰或者高锰酸钾，或者在石灰的碱性介质中处理毒形效果要好得多。过二硫酸钾是一种强氧化剂，与高锰酸钾相比，不仅抑制毒砂，而且活化黄铁矿，具有更长的最佳氧化时间，显示出极好的选择性。它在优先浮选中的特效与其双重性质有关，即过二硫酸钾与水相互作用，生成过一硫酸钾和硫酸钾，生成的过一硫有酸钾同样产生硫酸钾和活性双氧水。反应如下:

因矿浆碱度为8.5左右，这一条件使双氧水 分解并析出氧气，氧气与矿物(例如黄铜矿、黄铁矿、毒砂等)表面相互作用，产生适量的活性硫酸铜和单质硫，反应如下:渣浆泵厂家

所以过二硫酸钾的加入，不仅可以抑制毒砂，而且还可以借助所生成的硫酸铜与矿物作用以及所生成的单质硫活化黄铜矿和黄铁矿等矿物，使铜矿物和黄铁矿与毒砂实现最佳分选，从而提高金的回收率。

Oxidation inhibition of potassium persulfate by slurry pump

It is better to use a lot of lime or potassium permanganate, or in the alkaline medium of lime. Compared with potassium permanganate, potassium peroxydisulfate is a strong oxidant. Compared with potassium permanganate, it not only inhibits arsenopyrite, but also activates pyrite. It has a longer optimal oxidation time and shows excellent selectivity. Its special effect in preferential flotation is related to its dual properties, that is, potassium persulfate interacts with water to generate potassium persulfate and potassium sulfate, and potassium persulfate and potassium persulfate also generate potassium sulfate and active hydrogen peroxide. The reaction is as follows:

Because the pulp alkalinity is about 8.5, this condition makes hydrogen peroxide decompose and precipitate oxygen. Oxygen interacts with the surface of minerals (such as chalcopyrite, pyrite, arsenopyrite, etc.) to produce appropriate amount of active copper sulfate and elemental sulfur. The reaction is as follows: slurry pump manufacturer

Therefore, the addition of potassium persulfate can not only inhibit the arsenopyrite, but also activate the minerals such as chalcopyrite and pyrite with the help of the interaction between the generated copper sulfate and minerals and the generated elemental sulfur, so as to realize the best separation of copper minerals, pyrite and arsenopyrite, thus improving the recovery of gold.
