含石墨或碳质页岩金矿石的浮 渣浆泵选分离方法

含石墨或碳质页岩金矿石的浮 渣浆泵选分离方法是什么?
金矿中含石墨或碳质页岩会使浮选和金的提取过程复杂化。据估计,此类矿石约占全世界金矿的4%,属难选金矿。石墨进入金精矿后,在氰化过程中,它就会像贵金属的沉淀剂那样,从氰化溶液中将金沉积出来,并损失于氰化尾矿中。如果石墨在矿石中是以单独颗粒存在,不含有价的金,则可加起泡剂除去,若石墨呈极细粒存在于整个矿石中,这将会给分选和氰化带来相当大的困难。
26什么样的含银矿 石适宜用浮选法回收?
    当银矿物以辉银矿和自然银为主时,用浮选法和氰化法均可;对含有大量深红银矿、辉硒银矿.硒银矿等难于氰化的矿物,就只能用浮选方法:对铜、锌、铅硫化物含量高的矿石,也只能用浮选法。
27  有利于铂族元素分选时浮选的条件是什么?渣浆泵厂家
    浮选主要适用于选别硫化铂矿石。在许多情况下含铂矿物是可以用浮选法回收的,其中最难回收的是含铁、铜(铁铂矿与铜铂矿)的自然矿物。有时在铜-镍浮选的粗选尾矿中可发现硫镍铂钯矿、锑钯华、砷铂矿及一些其他矿物,为了回收这些含铂矿物,应该对铜镍粗选排出的尾矿进行补充浮选,用以造成更加有效的条件使铂矿物进入泡沫产物中。这些条件主要是:补加药剂及提高矿浆温度。铂矿物可以用重选法(溜槽、跳汰机等)从浮选尾矿中补充回收。
What is the method of separation of gold ore containing graphite or carbonaceous shale by slurry pump?
The process of flotation and gold extraction is complicated by the presence of graphite or carbonaceous shale in gold ore. It is estimated that this kind of ore accounts for about 4% of the world's gold deposits, and it is a refractory gold deposit. When graphite enters the gold concentrate, it will deposit gold from the cyanide solution and lose it to the cyanide tailings, just like the precipitant of precious metals. If graphite exists as a single particle in the ore and does not contain valuable gold, it can be removed by adding a foaming agent. If graphite exists as a very fine particle in the whole ore, it will bring considerable difficulties to separation and cyanidation.
What kind of silver bearing ore is suitable for recovery by flotation?
When silver minerals are mainly composed of argentite and natural silver, flotation and cyanidation can be used; for minerals containing a large number of deep red silver ore, selenite, selenite and other minerals that are difficult to cyanidate, flotation can only be used: for ores with high content of copper, zinc and lead sulfide, flotation can only be used.
27 what are the conditions for the flotation of platinum group elements? Slurry pump manufacturer
Flotation is mainly applied to the separation of platinum sulfide ore. In many cases, platinum bearing minerals can be recovered by flotation, among which the natural minerals containing iron and copper (iron and copper platinum ores) are the most difficult to recover. Sometimes, in the coarse tailings of copper nickel flotation, sulphur, nickel, platinum, palladium, Ti Bahua, arsenic and platinum ores and some other minerals can be found. In order to recover these platinum bearing minerals, flotation tailings from copper and nickel coarse separation should be floatation to make more effective conditions for platinum minerals to enter the foam products. These conditions are mainly: adding chemicals and increasing pulp temperature. Platinum minerals can be recovered from flotation tailings by gravity separation (chute, jig, etc.).
