選金廠 常用的渣漿泵活化劑是什么?
選金廠常用的話化劑有硫化鈉、硝酸鉛、酯酸鉛、硫酸銅等。國外廣泛應(yīng)用二氧化硫氣體作黃鐵礦浮選的活化劑。有的活化劑兼有抑制性能，比如硫化鈉既是含金氧化礦的活化劑，同時(shí)對(duì)自然金和各種硫化物礦物有抑制作用。因此，使用時(shí)要掌握好用量，不宜過大，最好分批添加。
33含金礦 石浮選時(shí)的適宜pH是多少?
礦漿pH往往直接或間接地影響礦物的可浮性，在一定條件下(藥劑濃度、礦漿溫度)，礦物可浮與不可得的pH界線叫做臨界pH.礦物的臨界pH隨浮選條件的改變而改變。常用的堿性礦漿調(diào)整劑是石灰、碳酸鈉、苛性鈉，酸性礦漿調(diào)整劑是硫酸。金的浮選多在堿性礦漿中進(jìn)行，因?yàn)樵谄菩缘V漿中黃藥不易分解，渣漿泵廠家硫化物礦氧化速度慢，礦漿中可溶性鹽的不利作用可以降低:對(duì)設(shè)備腐蝕性小。但是，有時(shí)也需要在酸性礦漿中浮選。比如，對(duì)于某些黃鐵礦和磁黃鐵礦礦石，在弱酸性礦漿中浮游能力比在堿性礦漿中要好;氰化尾礦的浮選多在pH為6的弱酸性礦漿中進(jìn)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.
