摘 要:H酸与芝加哥酸是同分异构体,它们有相同的分子式和相同的官能团,只是磺酸根取代位置不同,属同系列同分异构体。H酸对锡石的抑制能力很弱而对黄玉的抑制能力很强,因此用十一烷基1,1-二羧酸作捕收剂、用H酸作抑制剂,能从黄玉与锡石的混合物中浮出锡石。根据浮选药剂的同分异构原理,芝加哥酸与H酸有相同分子式和相同的官能团,只是官能团的取代位置异构,应具有与H酸相接近的抑制性能。试验结果表明二者对黄玉都具有极相近的抑制能力。H acid and Chicago acid are isomer body.They have the same molecular formula and functional group,but have the different place that sulfonate replace,so they belong to a homologous series of isomer body.H acid presents a very weak depress capability to cassiterite,but it have a very strong depress capability to topaz.Therefore,using undecyl 1,1-dicarboxylic acid as a collector and H acid as a depressant,that can flotate cassiterite from the mixture of topaz and cassiterite.According to the isomer principle of flotation agent,Chicago acid and H acid have the same molecular formula and functional group,but have the different place that functional group replace,so its depress capability should be similar with H acid.The experiment results show that they all possess the very approximate depress capability to topaz.
