Taking molybdenum tailings as the research object, the methods of recovering phlogopite on the base of comprehensive utilizations of other valuable minerals has been discussed. The best flotation condition includes that pulp density is 25%, the value of pH is 8.4, and the spindle speed of the batch flotation cell is 1850 r/min, sodium silicate is used as the silicate inhibitor, sodium oleate as collector, alkyl amine as the foaming agent. After cleaning and scavenging, the yield of the recovery and grade of concentrated phlogopite could be reached above 40% and 9.5%, and the yield of recovery and grade of scavenged phlogopite could be reached above 20% and 7.0%. The experimental research may provide the theoretical and experimental basis for phlogopite flotation from molybdenum tailings.

It is known that oxidation is one of the most common ways for penlandite to be introducted into tailing during traditional coarse-particle sulfide flotation. However, it could become much more complicated and challenging problems for the low-grade, fine-disseminated Cu-Ni sulfides containing Pt and Pd in Yunnan Mine, accompanied with more than 75% of the content of MgO in the ore sample is. Direct flotation tests had been conducted to extract the metallic values as much as possible by adding traditional depressants and collectors, such as carboxylmethyl cellulose, starch, sodium silicate, butyl xanthate, (BX), butyl ammonium dithophosphate (BA) and etc., the relatively satisfied recoveries of Cu, Ni, Pt and Pd in the concentrate from bench flotation tests were obtained, however, more than 30% of metallic values still lost in the slime. In this study, bench flotation tests for the ore sample fromYunnan Mine, micro-flotation tests of serpentines and pentlandite from Jinchuan Mine and their settling rate tests were conducted to figure out how the oxidation influence the recovery of the ultra-fine nickel sulfide. All the tests results pointed to the presence of over-oxidation on the ultra-fine nickel sulfide surface and lead to the loss of Ni containing Pt and Pd in the slime tailing. Some methods which tried to slow the speed of oxidation on mineral surface during grinding and flotation were introduced in order to recover the values before over-oxidation of sulfides; however, the slime coating of serpentines also may play an important role in disturbing the floatability of ultra-fine sulfide.

This article research a low grade ore in Jinping, it contain 0.634% nickel, 0.329% copper, 0.047% cobalt, 30.18% SiO2, and 19.72% MgO. The rude ore contain amount of gangue minerals such as chlorite, mica, quartz, feldspar, which are easily slimed and have undesirable effect on flotation. In order to decrease such negative effect, this article investigated a method by “desliming-flotation” test, flotation test. Finally find that direct flotation is a promising method when utilizing carboxymethyl cellulose and sodium silicate as combinatorial depressants. And obtained the grade of bulk concentrate is 2.96% with recovery 60.82%, the recovery increased 2.43% compare with “desliming-flotation” test.

In this study, the single mineral flotation experiments of magnesite and its associated minerals including dolomite, serpentine, talc and quartz were conducted, and the influences of the dosage of collectors such as sodium oleate and lauryl amine, pH value and the influences of regulars such as sodium hexametaphosphate and sodium silicate on those minerals were researched. According to the results, a process to reduce the content of gangue minerals was proposed, which at first use lauryl amine as a collector to remove most talc and quartz and part of the dolomite and serpentine, and then use sodium oleate as a collector to separate magnesite from dolomite and serpentine. This is a theoretical reference for the beneficiation of magnesite.
