本文研究了方铅矿浮选过程中各种电化学环境的影响。电化学环境由用于研磨方铅矿矿石的球磨机和用于在实验室规模中浮选方铅矿的Denver浮选槽组成。为了实现硫代硫酸钠的最大回收率，已使用0.06和0.12M的空气和氮气浓度来控制Denver浮选槽中的矿浆电位。方铅矿样品来自伊朗北部Kiyasar地区的“Era矿”。此矿包含：方铅矿（PbS）至少22%，萤石（CaF 2）73.37%，石英（SiO2）2.54%，以及其他矿物如白铅矿（PbCO 3）和高岭石（Al 2Si 2 O 5（OH）4）。方铅矿的浮选在0.12M硫代硫酸钠溶液中进行。结果表明，在有和无戊基黄原酸钾（KAX）存在下，在电位280 ~ 350 mV时，回收率分别为85%和63%，在有和无捕收剂（KAX）存在下，在电位175 ~ 210 mV时，回收率分别为70%和52%。
In this paper, the effect of various electrochemical environments in the galena flotation is investigated. The electrochemical environments consisted of a ball mill for grinding of galena ore and a Denver flotation cell for flotation of galena in the laboratory scale. In order to achieve the maximum recovery with sodium hyposulfite, the concentrations of 0.06 and 0.12M of air and nitrogen gases have been used to control the pulp potential in the Denver flotation cell. The galena sample was from the “Era mine” which is located in the Kiyasar area, north of Iran. This mine contains: Galena (PbS) at least 22%, Fluorite (CaF2) 73.37%, Quartz (SiO2) 2.54% and other minerals such as Cerussite (PbCO3) and Kaolinite (Al2Si2O5(OH)4). Flotation of Galena was conducted in a 0.12M of sodium hyposulfite solution. It was found that the amount of recovery by this process was 85% and 63% in the presence and absence of potassium amyl xanthate (KAX) and at an estimated potential of 280 to 350mV respectively while the recovery was 70% and 52% at an approximate potential of 175 to 210mV in water in the presence and absence of collector (KAX).
