许多铜矿物使用异丙基黄酸钠(SIPX)作捕收剂。它在某种程度上可能浮起一些不需要的矿物,如黄铁矿。FLRX31是化学性质得到改进的SIPX。它的许多化学性质和SIPX相同。但是它不仅改进了铜的回收率而且将黄铁矿排除在精矿外。它的用量比SIPX少50%。铜活化矿物,如闪锌矿和砷黄铁矿采用FLEX31也能提高回收率。但是在活化前采用这两种药剂分离铜和这些矿物获得的结果相似,没有达到使用其他药剂可能得到的最好指标。对铜/锌、砷黄铁矿和铜/钼矿石进行了试验。
Many copper minerals use sodium propyl sulfonate (SIPX) as a collector. It may to some extent float some unwanted minerals, such as pyrite. FLXX31 is SIPX with improved chemical properties. It has many of the same chemical properties as SIPX. However, it not only improves copper recovery but also excludes pyrite from the concentrate. It uses 50% less than SIPX. Copper-activated minerals, such as sphalerite and arsenopyrite, also increase recovery with FLEX31. However, the isolation of copper from these two agents prior to activation was similar to the results obtained with these minerals and did not meet the best possible indicator for the use of other agents. Copper / zinc, arsenic pyrite and copper / molybdenum ore were tested.
