一、矿浆中硫化钠的检测与自动调节多金属氧化矿及混合矿的浮选中,活化剂硫化钠的加入量直接影响浮选指标.加入量过少,硫化不充分;加入量过多则抑制有用矿物.为了使浮选作业在最佳硫化条件下进行,以利金属选别达到较高指标,我们使用硫电极检验浮选槽矿浆中残余硫离子浓度,根据矿石性质的变化自动调节硫化钠的添加量. 检测与控制原理如方框图一.采用硫离子选择性电极测出矿浆中残余硫离子浓度的电位值E,由Nernst方程:E=E_o+Sloga_i
First, the detection and automatic adjustment of sodium sulfide in the ore In the flotation of multi-metal oxide ore and mixed ore, the amount of activator sodium sulfide directly affects the flotation index.Add too little, inadequate curing; excessive dosage is Inhibition of useful minerals. In order to optimize the curing conditions in the flotation process to Lee metal sorting to achieve higher targets, we use the sulfur electrode test flotation tank residual sulfur ion concentration, according to changes in the nature of the ore automatically adjust the vulcanization The amount of sodium added. Detection and control principles such as the block diagram of a sulfur ion selective electrode measured residual sulfur ion concentration in the pulp of the potential value E, by the Nernst equation: E = E_o + Sloga_i
