研究了用廉价的热带植物油脂肪酸从矿石和中矿中,浮选回收锡石、钛铁矿、黑钨矿和赤铁矿的可能性。对下述植物油做过试验:芒果油、野生胡椒油、蓖麻子油、花生油、椰子油、米糠油、桐油。所进行的实验表明,芒果油是此油酸强的且有选择性的捕收剂;在500克/吨的油酸用量下,黑钨矿回收率低至17％;而在同样的芒果油用量 The possibility of flotation recovery of cassiterite, ilmenite, wolframite and hematite from ores and ores using inexpensive tropical vegetable oil fatty acids was studied. The following vegetable oils were tested: mango oil, wild pepper oil, castor oil, peanut oil, coconut oil, rice bran oil, tung oil. The experiments carried out showed that mango oil is a strong and selective collector of this oleic acid; the wolframite recovery was as low as 17% at a dosage of oleic acid of 500 g / t; whereas in the same mango oil Amount
