大量发表的文献,仅在某些特殊的场合,才报道关于矿浆温度对分选结果的影响。同样,高于室温的浮选过程在工业上的应用则是罕见的和极个别的。较早的例子是由铜精矿中分离副产品辉钼矿,该过程始于1933年。其它所熟知的例子包括:赤铁矿精矿的精选、稀土矿物的浮选以及用SO_2方法从含铁硫化矿物中分选闪锌矿。矿浆升温的热量消耗在10～100℃范围内,一般矿石中矿物的比热小于0.2卡/克/℃。如石英0.188,黄铁矿0.135卡/克/℃。一般可采取0.2卡/克/℃。图1系在不同浓度条件下,将矿浆由10℃加
A large number of published literature, only in some special occasions, reported on the pulp temperature on the sorting results. Similarly, industrial applications of the flotation process above room temperature are rare and unusual. Earlier examples were the separation of by-product molybdenite from copper concentrates, which started in 1933. Other well-known examples include the selection of hematite concentrates, the flotation of rare earth minerals and the separation of sphalerite from ferrous sulphide minerals by the SO 2 process. The calorie consumption of slurry heating is in the range of 10 ~ 100 ℃. The specific heat of minerals in general ore is less than 0.2 cal / g / ℃. Such as quartz 0.188, pyrite 0.135 card / g / ℃. Generally can take 0.2 card / g / ℃. Figure 1 Department of the different concentrations of the conditions, the pulp from 10 ℃ plus
