Abstract

In this study, grinding + flotation experiments were performed on the sample of complex Pb-Zn sulphide ore taken from Niğde (Ulukışla-Madenköy) region in Turkey. According to the mineralogical analysis of the ore sample used in experimental studies, it was determined that the ore composition contains calcite, quartz, pyrite, chalcopyrite, hematite, goethite, limonite, gypsum, galena, sphalerite, jarosite, arsenopyrite and marcasite minerals. In addition, Au and Ag grains were found to be inclusions in hematite, goethite and jarosite minerals. The experiments were carried out at a solid ratio of 30%, a flow rate of 10 L/min, a stirring rate of 1250 rpm and pH = 9. In flotation tests, lime is used as the pH regulator, zinc sulphate, sodium silicate as the depressant, sodium isobutyl dithiophosphine as the collector and methyl isobutyl carbinol as the frother. In the flotation studies, the effect of Aerophine 3418A collector dosage on flotation was investigated. As a result, a lead concentrate of 55.13% Pb was obtained and it was found that this concentrate contained 2489 ppm of Ag. The amount of Aerophine 3418A collector was determined as 10 g/t.

Aerophine 3418A捕收剂用量对Niğde (Ulukışla-Madenköy)复合铅锌硫化矿浮选的影响

本文对土耳其Niğde (Ulukışla-Madenköy)地区某复杂铅锌硫化矿进行了磨矿+浮选试验。根据实验研究所用矿石样品的矿物学分析，确定矿石成分为方解石、石英、黄铁矿、黄铜矿、赤铁矿、针铁矿、褐铁矿、石膏、方铅矿、闪锌矿、黄钾铁矾、毒砂和黄铁矿等矿物。此外，在赤铁矿、针铁矿和黄钾铁矾矿物中发现了Au和Ag颗粒的包裹体。实验条件为固相比为30%，流速为10 L/min，搅拌速率为1250 rpm, pH = 9。浮选试验以石灰为pH调节剂，硫酸锌、水玻璃为抑制剂，异丁基二硫代膦钠为捕收剂，甲基异丁基甲醇为起泡剂。在浮选研究中，考察了Aerophine 3418A捕收剂用量对浮选的影响。结果表明，该铅精矿铅含量为55.13%，银含量为2489 ppm。测定Aerophine 3418A捕收剂用量为10 g/t。
