什么是碳酸化转化浮选法渣浆泵提金技术?

将含金钢铅精矿放入碳酸钠(或碳酸铵)的溶液中，恒温搅拌非通入密气，使钢形成铜铵络离子被浸出，而方铅矿中的铅则转化为碳酸铅，然后过滤除铜，铜液用褐煤吸附，炼成金属铜，也可用硫化铵沉淀得纯硫化铜。过滤的渣先用浮选法回收黄铁矿，得到硫精矿，尾矿即碳酸铅，用硅氟酸溶解，其中的碳酸铅也被溶解了，然后过滤除渣。溶液即是硅氟酸铅，再加入硫酸，生成硫酸铅，可继续加工成化工产品，也可以外销。最后的过滤渣经焙烧，氰化浸出提金。

什么是混汞浮选法?
游高金的混汞浮选过程如图4. 1所示。

低品位金矿石磨矿分级后，矿浆与用电化学方法分散的汞一起搅拌。在搅拌过程中游离的金粒子与分散在矿浆中的汞粒子混汞，搅拌以后分浆浮选，没有混汞的金进入一个回路，已混汞的金进入另一回路，捕收剂用戊基黄药和乙基黄药(1 : 1)，两个回路的精矿合并在一起为最终精矿。这是回收低品位金的一种方法，从300t/d规模的工业试验情况来看，此法在经济上是合算的。汞的用量不高，一般为2.5~4g/t; 金的回收率与原矿品位有关，原矿品位从1.29g/t 上升到L.8g/t时，回收率由80.07%增加到87.81%。
17含金黄铁矿浮选过程中矿浆电位有何重要作用?

含金硫化矿的浮选实质上是浮选载金矿物例如黄铁矿、黄铜矿、毒砂、方铅矿等以及部分呈游离状态的自然金。在此过程中，研究发现矿浆电位Eh起着非常重要的作用。捕收剂诸如黄药、黑药或者这两种药剂的混合物在阳极形成硫化矿物的疏水膜，该阳极过程与阴极过程例如氧的还原相互陪伴，使得浮选回收率与矿浆电位紧密地联系在一起。渣浆泵

除了可以通过矿 浆中的氧气控制电位外。还可以采用化学药剂控制电位。所用的药剂一般有硫化钠、连二亚硫酸钠、二氧化硫和

What is the technology of gold extraction by slurry pump of carbonation conversion flotation?

The lead concentrate containing steel is put into the solution of sodium carbonate (or ammonium carbonate), stirred at constant temperature without passing through dense gas, so that the copper ammonium complex ion formed in steel is leached, while the lead in galena is transformed into lead carbonate, and then the copper is filtered and removed, and the copper solution is absorbed by lignite, and refined into copper metal, or precipitated with ammonium sulfide to obtain pure copper sulfide. The pyrite is recovered from the filtered slag by flotation to obtain sulfur concentrate. The tailings, namely lead carbonate, are dissolved by silicofluoric acid, and the lead carbonate is also dissolved, and then the slag is removed by filtration. The solution is lead silicofluoroate, and then sulfuric acid is added to produce lead sulfate, which can be processed into chemical products or exported. The final filter residue is roasted and cyanide leached to extract gold.

What is mixed mercury flotation?

The flotation process of mixed mercury with high gold is shown in Fig. 4.1.

After grinding and grading of low-grade gold ores, the pulp is stirred with mercury dispersed by electrochemical method. During the mixing process, the free gold particles are mixed with the mercury particles dispersed in the slurry. After the mixing, the slurry is separated for flotation. The gold without mercury mixture enters one circuit, and the gold mixed with Mercury enters another circuit. The collector uses amyl xanthate and ethyl xanthate (1:1). The refined ores of the two circuits are combined to form the final concentrate. This is a method of recovering low-grade gold. From the industrial test of 300t / D scale, this method is economical. The amount of mercury is not high, generally 2.5 ~ 4G / T; the recovery rate of gold is related to the grade of raw ore. when the grade of raw ore rises from 1.29g/t to l.8g/t, the recovery rate increases from 80.07% to 87.81%.

What is the important role of pulp potential in the flotation of 17 gold bearing pyrite?

In essence, the flotation of gold bearing sulfide ore is the flotation of gold bearing minerals such as pyrite, chalcopyrite, arsenopyrite, galena and some free natural gold. In this process, it is found that pulp potential eh plays a very important role. The collector such as xanthate, black agent or the mixture of the two agents forms a hydrophobic membrane of sulfide minerals at the anode. The anode process and the cathode process such as oxygen reduction are accompanied each other, so that the flotation recovery is closely related to the pulp potential. Slurry pump

In addition to controlling the potential through oxygen in the pulp. Chemical agents can also be used to control the potential. Generally, the reagents used are sodium sulfide, sodium hydrosulfite, sulfur dioxide and
