选金厂 常用的渣浆泵活化剂是什么?

选金厂常用的话化剂有硫化钠、硝酸铅、酯酸铅、硫酸铜等。国外广泛应用二氧化硫气体作黄铁矿浮选的活化剂。有的活化剂兼有抑制性能，比如硫化钠既是含金氧化矿的活化剂，同时对自然金和各种硫化物矿物有抑制作用。因此，使用时要掌握好用量，不宜过大，最好分批添加。
33含金矿 石浮选时的适宜pH是多少?
    矿浆pH往往直接或间接地影响矿物的可浮性，在一定条件下(药剂浓度、矿浆温度)，矿物可浮与不可得的pH界线叫做临界pH.矿物的临界pH随浮选条件的改变而改变。常用的碱性矿浆调整剂是石灰、碳酸钠、苛性钠，酸性矿浆调整剂是硫酸。金的浮选多在碱性矿浆中进行，因为在破性矿浆中黄药不易分解，渣浆泵厂家硫化物矿氧化速度慢，矿浆中可溶性盐的不利作用可以降低:对设备腐蚀性小。但是，有时也需要在酸性矿浆中浮选。比如，对于某些黄铁矿和磁黄铁矿矿石，在弱酸性矿浆中浮游能力比在碱性矿浆中要好;氰化尾矿的浮选多在pH为6的弱酸性矿浆中进行。

What is the activator of slurry pump commonly used in gold concentrator?

The commonly used reagents in gold concentrators are sodium sulfide, lead nitrate, lead ester, copper sulfate, etc. Sulfur dioxide is widely used as activator in pyrite flotation abroad. For example, sodium sulfide is not only an activator of gold bearing oxidized ore, but also an inhibitor of natural gold and various sulfide minerals. Therefore, the use of a good grasp of the amount, not too large, the best batch add.

What is the suitable pH value for flotation of 33 gold bearing ore?

Pulp pH often directly or indirectly affects the floatability of minerals. Under certain conditions (reagent concentration, pulp temperature), the boundary between floatable and unavailable pH of minerals is called critical pH. the critical pH of minerals changes with the change of flotation conditions. Lime, sodium carbonate and caustic soda are commonly used as the basic pulp regulator, while sulfuric acid is used as the acid pulp regulator. The flotation of gold is mostly carried out in the alkaline pulp, because the xanthate is not easy to decompose in the destructive pulp, the oxidation speed of sulfide ore in the slurry pump factory is slow, and the adverse effect of soluble salt in the pulp can be reduced: the corrosion to the equipment is small. However, sometimes flotation in acid pulp is also required. For example, for some pyrite and pyrrhotite ores, the floating capacity in weak acid pulp is better than in alkaline pulp; the flotation of cyanide tailings is mostly carried out in weak acid pulp with pH 6.
