我國(guó)AF泡沫泵含金礦石的浮選試驗(yàn)或生產(chǎn)大多采用了組合捕收劑。如招遠(yuǎn)河?xùn)|金礦，原浮選流程采用丁基黃藥作捕收劑，浮選回收率為93. 19%，當(dāng)改用異戊基黃藥與丁基銨黑藥組合時(shí)，回收率提高至94.44%，增加了1. 25%。銅錫山金礦的氧化礦，單獨(dú)使用丁基黃藥時(shí)，其用量為200g/t,當(dāng)它與丁基銨黑藥組合使用時(shí)(1 : 3)，其用量降為140~ 150g/t,且精礦含金由107.5g/t 提高至114. 08g/t,回收率由71. 8%提高至75.43%，提高了3.63%。龍水金礦提高回收率的措施之一是將丁基黃藥與丁基銨黑藥的組合比，由原來(lái)的3:1改為6:1。靈寶縣金礦選廠，由于原礦含金由5g/t降至3g/t，采用混汞-浮選流程，金的總回收率只有 80%，當(dāng)采用組合捕收劑(基黃藥與丁星鉸黑藥)取代原單一捕收劑的措施后，使金的總回收率達(dá)到85.86%，提高了5.86%。河南基合金硫化礦石英脈礦石選廠，粗選時(shí)以丁基黃藥與丁基銨黑藥進(jìn)行浮迎，然后年增加中性油進(jìn)行第二步粗選以回收難選會(huì)，從而使會(huì)的融回收率達(dá)89.29%山東某石英限金的浮流證明，無(wú)論是硫化收劑還是氧化礦礦石，添加烴油作輔助捕收劑很有好處，當(dāng)黃藥與黑藥的用量為80g/t和100g/t 時(shí)， 添加與不添加烴油相比，金的回收率提高3.91%以上;對(duì)氧化率為43%的含金石英脈礦石，在使用丁基黃藥與丁基銨黑藥的基礎(chǔ)上，再添加35號(hào)捕收劑(為含經(jīng)肟酸和黑藥的藥劑)，在AF泡沫泵藥劑用量相近的情況下，金的回收率由75. 20%提高到82. 60%。

Most of the flotation tests or production of gold bearing ores of AF foam pump in China are combined collectors. For example, in Hedong Gold Mine of Zhaoyuan, butyl xanthate was used as collector in the original flotation process, and the recovery was 93.19%. When the combination of Isoamyl xanthate and butylammonium was used, the recovery was increased to 94.44%, 1.25%. When butyl xanthate is used alone, the dosage of oxidized ore in tongxishan gold mine is 200g / T. when it is combined with butylammonium black drug (1:3), the dosage is reduced to 140-150g / T, and the gold content in concentrate is increased from 107.5g/t to 114.08g/t, the recovery is increased from 71.8% to 75.43%, and the recovery is increased by 3.63%. One of the measures to improve the recovery of Longshui gold mine is to change the combination ratio of butyl xanthate and Butyl Ammonium black drug from 3:1 to 6:1. In Lingbao gold ore dressing plant, the total recovery rate of gold is only 80% because the gold content of the raw ore is reduced from 5g / T to 3G / T by using the process of mixed mercury flotation. When the combined collector (basic xanthate and dingxingzhi black agent) is used to replace the original single collector, the total recovery rate of gold is 85.86%, which is increased by 5.86%. In Henan base alloy sulfide quartz vein ore dressing plant, butyl xanthate and butylammonium black agent are used for flotation during roughing, and then neutral oil is added for the second step of roughing in order to recover the refractory ore, so that the recovery rate can reach 89.29%. The floating flow of a certain quartz gold limit in Shandong province proves that it is very beneficial to add hydrocarbon oil as auxiliary collector whether it is sulfide collector or oxidized ore When the dosage of black medicine is 80g / T and 100g / T, the recovery of gold is increased by more than 3.91% compared with that without hydrocarbon oil; For gold bearing quartz vein ore with oxidation rate of 43%, based on the use of butyl xanthate and Butyl Ammonium black, adding No. 35 collector (containing oxime acid and black medicine), the recovery rate of gold is increased from 75.20% to 82.60% when the dosage of AF foam pump is similar.
