9含金黃鐵礦和磁渣漿泵黃鐵礦如何浮選分離?
含金銅硫硫化礦石較多，自然金大部分呈細(xì)粒賦存于黃銅礦、黃鐵礦中，常采用優(yōu)先或混合浮選工藝流程，在分離時，加入石灰來抑制黃鐵礦，浮選硫化銅礦物，得到合格的含金銅、硫精礦。
含金銅鉛鋅硫化礦石，一般采用銅鉛部分混合浮選工藝，再將銅沿混合精礦進(jìn)行分離，得到銅、鉛精礦，金常富集在銅精礦中。有的銅鉛混合精礦，由于銅、鉛硫化礦物可浮性相近，共生關(guān)系比較復(fù)雜，難以浮選分離， 得不到合格的含金銅、鉛精礦?？蓪⒑疸~鉛混合精礦，采用碳酸化轉(zhuǎn)化-浮選法提金，使銅鉛得到分離，綜合回收金、銀等貴重金屬。
含金銅鐵礦石，主要礦物是黃銅礦及磁鐵礦，而自然金呈微細(xì)粒賦存于黃銅礦中，可用浮選-磁選聯(lián)合工藝流程來進(jìn)行處理，分別得到含金銅精礦和鐵精礦等兩種產(chǎn)品。
8含有硫化礦的含 金石英脈礦石如何浮選
浮選含有硫化礦的含金石英脈礦石時，可采用乙基或丁基黃藥作捕收劑進(jìn)行混合浮選，而對于稍受氧化的礦石則宜采用戌基黃藥進(jìn)行浮選，也可采用某種烴基硫代磷酸鹽作為輔助捕收劑。渣漿泵廠家
含金黃鐵礦與磁黃鐵礦的分離可往礦漿中強(qiáng)烈吹入空氣，用石灰抑制這兩種礦物，然后用蘇打選擇性地活化黃鐵礦，磁黃鐵礦氧化時，表面迅速形成一層年固的親水氧化膜，而前鐵礦表面形成的親水氧化膜，在蘇打介質(zhì)中則被清洗，因其所生成的碳酸鹽易從表面脫落下來。
How to separate gold bearing pyrite and magnetic slurry pump pyrite?
There are many gold bearing copper sulfide ores, and most of the natural gold occurs in chalcopyrite and pyrite as fine particles. The preferred or mixed flotation process is often adopted. During separation, lime is added to restrain pyrite and flotation copper sulfide minerals to obtain qualified gold bearing copper and sulfur concentrate.
Copper and lead concentrates are usually obtained from gold bearing copper lead zinc sulfide ores by partial mixed flotation of copper and lead and separation of copper along the mixed concentrate. Due to the similar floatability and complex symbiosis of copper and lead sulfide minerals, some copper and lead mixed concentrates are difficult to be separated by flotation, so qualified gold bearing copper and lead concentrates cannot be obtained. Gold can be extracted from gold bearing copper lead mixed concentrate by carbonation conversion flotation method, so that copper lead can be separated and gold, silver and other precious metals can be recovered comprehensively.
The main minerals of gold bearing copper iron ore are chalcopyrite and magnetite, while the natural gold occurs in chalcopyrite as fine particles, which can be treated by the combined process of flotation and magnetic separation to obtain two kinds of products, namely gold bearing copper concentrate and iron concentrate.
How to flotation gold bearing quartz vein ore containing sulfide ore
In the flotation of gold bearing quartz vein ore containing sulfide ore, ethyl or butyl xanthate can be used as collector for mixed flotation, while for slightly oxidized ore, Xu based xanthate can be used for flotation, or a certain hydrocarbon based thiophosphate can be used as auxiliary collector.

The separation of auriferous pyrite and pyrrhotite can strongly blow air into the pulp, inhibit the two minerals with lime, and then selectively activate pyrite with soda. When pyrrhotite is oxidized, a layer of annual solid hydrophilic oxide film is rapidly formed on the surface, while the hydrophilic oxide film formed on the surface of the former iron ore is cleaned in the soda medium, because the carbonate generated is easy to be removed from the surface Fall down.
