含金矿石浮选渣浆泵的基本过程是什么?
    浮选过程一般包括 下列内容:
    ①物料的准备，以磨矿分级为主，目的是使金物单体分离，控制粒度和矿浆浓度，使适合浮选的要求:
    ②调整矿浆pH并加入浮选剂，满足分选所需要的药剂条件:

③搅拌充气，造成大量的矿化泡沫，以使金矿物和泡沫充分接触和附着;

④稳定的矿比泡沫层的形成和刮出，实现金矿物和脉石矿物的有效分离。

正常情况下，浮选的泡沫产物作为精矿产出，这种方法称为正浮选。但有时也可以将脉石矿物浮入泡沫产物中，而将有用心物留在矿浆中作为精矿排出。这种与正常脉常浮选相反的浮选过程称为反浮选。
7  含金多金属硫化矿物的主要类型有那些?主要的分选方法是什么?
    根据含金多金属硫化矿物的共生关系，含金矿石主要类型及伴生金属、脉石矿物见表4.1。

各种矿石类型中，金的伴生金属硫化矿物主要是黄铜矿及黄铁矿。

含金多金属硫化矿主要分为含金铜硫矿石、含金铜铝锌矿石、锑金(砷) 矿石、锑钨金矿石等。在含金多金属硫化矿中，粗粒的自然金一般常用重选回收。但大部分自然金是以细粒浸染状赋存于黄铜矿、黄铁矿、毒砂、辉锑矿、方铅矿等硫化矿物中，它们紧密共生，有的还呈包裹体，在选矿过程中，金随着这些金属硫化矿物富集而富集，只能得到含金的铜、铅、锑、硫等硫化矿物精矿。渣浆泵含金硫精矿，如焦家、招远、新城、五龙、金厂峪、灵山、乳山等金矿选厂均采用氰化浸出提金;而龙水金矿选厂则采用硫脲浸出提金。以上两种方法的浸出渣均为硫精矿，作为生产硫酸的原料。其他含金硫化矿物精矿，只有在冶炼过程中加以综合回收金。

What is the basic process of gold bearing ore flotation slurry pump?

The flotation process generally includes the following contents:

① The preparation of materials is mainly based on grinding and classification. The purpose is to separate the gold monomer, control the particle size and pulp concentration to meet the requirements of flotation:

② Adjust pulp pH and add flotation agent to meet the reagent conditions required for separation:

3. Agitation and aeration cause a large amount of mineralized foam to fully contact and adhere gold minerals and foam.

4. Stable ore is better than foam layer formation and scraping to achieve effective separation of gold minerals and gangue minerals.

Under normal circumstances, the flotation of foam products as concentrate output, this method is called positive flotation. But sometimes gangue minerals can be floated into foam products, and there will be intentions to remain in the pulp as the concentrate. The reverse flotation process is called reverse flotation.

What are the main types of gold bearing polymetallic sulfide minerals? What are the main separation methods?

According to the paragenesis of gold bearing polymetallic sulfide minerals, the main types of gold bearing ores, associated metals and gangue minerals are shown in table 4.1.

Among various ore types, the associated metal sulfide minerals of gold are mainly chalcopyrite and pyrite.

Gold bearing polymetallic sulfide ores are mainly divided into gold bearing copper sulfide ores, gold bearing copper aluminum zinc ores, antimony gold (arsenic) ores, antimony tungsten gold ores, etc. In the gold bearing polymetallic sulfide ores, the coarse natural gold is usually recovered by gravity separation. However, most of the natural gold occurs in chalcopyrite, pyrite, arsenopyrite, stibnite, galena and other sulfide minerals in fine-grained disseminated form. They are closely related and some are inclusions. During the beneficiation process, gold is enriched with these metal sulfide minerals, and only copper, lead, antimony, sulfur and other sulfide mineral concentrates containing gold can be obtained. The gold bearing sulfur concentrate of the slurry pump, such as Jiaojia, Zhaoyuan, Xincheng, Wulong, Jinchangyu, Lingshan, Rushan and other gold ore dressing plants, uses cyanide leaching to extract gold, while the Longshui gold ore dressing plant uses thiourea leaching to extract gold. The leached residue of the above two methods is sulfur concentrate, which is used as raw material for sulfuric acid production. Other gold bearing sulfide mineral concentrates can only be recovered comprehensively in the smelting process.
