现继续介绍采用搜索法对石灰乳进行控制的过程。图48是搜索法控制的示意图。48图上横座标为石灰乳用量,并在允许范围内,把它分成若干等分。每等分的大小为△q。纵座标为铜的回收率。假设最初石灰乳用量较小,髓着用量增加,矿浆pH值增高;在强碱性的矿浆中,黄药得到较充分的解离,使起捕收作用的黄原酸离子浓度增加,另一方面,随着石灰乳用量的增加,黄铁矿被更多地抑制,又减少了它对黄药的消耗,所以从石灰
Now continue to introduce the use of search method to control the process of milk of lime. Figure 48 is a schematic diagram of search method control. The figure on the horizontal axis is the amount of milk of lime, and within the allowable range, it is divided into several aliquots. The size of each decile △ q. The ordinate is copper recovery. Assuming that the initial amount of lime milk is small, the amount of pulp increases, and the pH value of the pulp increases. In strong alkaline pulp, the xanthate is more fully dissociated, increasing the concentration of xanthogenic acid that has the effect of harvesting. As the quantity of milk of lime increased, the pyrite was more suppressed and the consumption of xanthate was reduced. Therefore,
