什么叫渣漿泵浮選藥劑的“ 協(xié)同效應(yīng)"?
不同的藥劑在浮選過(guò)程中作用不同，藥劑作用除了有捕收、起泡和調(diào)整等作用的區(qū)別以外，即使是同一類(lèi)型的藥劑， 往往也使用兩種以上。例如捕收劑，很多資料表明，混合用藥比單一用藥嬰好。這種現(xiàn)象為“協(xié)同效應(yīng)”。如有關(guān)研究成果和生產(chǎn)實(shí)踐表明，將丁基黃藥和丁基銨黑藥兩種藥劑混合使用，比單獨(dú)添加其中任何一種藥劑都好， 金的回收率都有明顯的提高。如浙江某金選廠，在采用丁基銨黑藥和丁基黃藥混合比例為2:1 (1.6g/t. 59g/)時(shí)，金、銀回收率分別達(dá)到97.37%和91. 86%，比原來(lái)提高了7.11% 和10.52%，同時(shí)精礦中金、銀品位也有很大幅度的提高。
35分散劑在含金礦石浮選中的作用是什么?
礦物細(xì)泥對(duì)浮選過(guò)程干擾尤為顯著，一方面，不同礦物彼此之間黏結(jié)，凝聚成團(tuán)，破壞了整個(gè)浮選過(guò)程的選擇性，使精礦質(zhì)量降低;另一方面微細(xì)礦泥會(huì)大量吸附于有用礦物表面，形成礦泥薄膜，阻止藥劑與礦粒表面接觸，降低礦物的可浮性，影響回收率。此外，礦泥比表面積大，消耗大量藥劑。對(duì)以上情況除可以用機(jī)械分級(jí)辦法將礦泥脫除外，還可添加分散劑消除礦泥的有害影響。如水玻璃、碳酸鈉、硫化鈉等能增強(qiáng)礦泥表面親水性，加大微細(xì)顆粒彼此團(tuán)聚的能力，從而減輕其絮凝和罩蓋作用。這是改善浮選條
件、提高細(xì)粒級(jí)選別回收率的有效途徑。
36石灰在含金礦 石浮選過(guò)程中的作用是什么?渣漿泵廠家
在浮選過(guò)程中，石灰可以起到pH調(diào)整劑、抑制劑、凝聚劑和絮凝劑等的作用。在含金礦石的浮選過(guò)程中，石灰同樣起著非常重要的作用，主要是用來(lái)作為pH調(diào)整劑和抑制劑，改善金礦石的浮選。
What is the "synergistic effect" of slurry pump flotation reagents?
Different reagents have different functions in the flotation process. Apart from the differences in the functions of collection, foaming and adjustment, more than two kinds of reagents are often used even for the same type of reagents. For example, collectors, many data show that the combination of drugs is better than single drug infants. This phenomenon is called "synergistic effect". For example, the relevant research results and production practice show that the mixture of butyl xanthate and Butyl Ammonium black medicine is better than any of them alone, and the recovery rate of gold is significantly improved. For example, in a gold concentrator in Zhejiang Province, when the mixture ratio of butylammonium black drug and butylammonium yellow drug is 2:1 (1.6g / T. 59G /), the recovery of gold and silver are 97.37% and 91.86% respectively, which are 7.11% and 10.52% higher than the original, and the grade of gold and silver in the concentrate is also greatly improved.
What is the function of 35 dispersant in gold ore flotation?
On the one hand, different minerals adhere to each other and agglomerate, which destroys the selectivity of the whole flotation process and reduces the quality of concentrate; on the other hand, a large number of fine slimes will be adsorbed on the surface of useful minerals, forming slime film, preventing the agent from contacting with the surface of ore particles, reducing the floatability of minerals and affecting the recovery rate. In addition, the specific surface area of slime is large and a large amount of chemicals are consumed. In addition to mechanical classification, dispersant can be added to eliminate the harmful effect of slime. For example, water glass, sodium carbonate, sodium sulfide and so on can enhance the surface hydrophilicity of slime, increase the ability of agglomeration of fine particles, so as to reduce its flocculation and capping effect. This is to improve the flotation strip
An effective way to improve the recovery rate of fine-grained separation.
What is the role of 36 lime in the flotation of gold bearing ores? Slurry pump manufacturer
In the flotation process, lime can play the role of pH regulator, inhibitor, coagulant and flocculant. In the flotation process of gold ore, lime also plays a very important role. It is mainly used as pH regulator and inhibitor to improve the flotation of gold ore.
