In the production of sodium silicate flotation test and copper oxide ores, plays the role of a dispersion of fine clay, although it can not be increased to the level of the flotation concentrate recovery of copper sulfide, but it is efficiently dispersed in Ore The mud group makes the effect of the separation of the mines significantly improved, the flotation operation process is stable, and the recovery rate of the concentrate is improved. The mechanism of water glass as a slime dispersant is because its silicic acid granules are negatively charged and have a hydration layer on the surface, so that the silicate granules can be stably dispersed and suspended in the slurry without agglomeration and mutual agglomeration. settlement. When the colloidal particles and HSiO 3 - are adsorbed on the surface of the slime, the slime is dispersed. Sodium silicate is quartz, silicate and aluminosilicate minerals inhibitor, but it is also sludge dispersant. In the copper-sulfur separation test, water glass was used as an inhibitor of gangue minerals to strengthen copper-sulfur flotation separation. The copper concentrate grade was increased by 0.61% compared with the lime process, and the recovery rate was equivalent. It can be seen that when the amount of slime is large, the addition of water glass during copper-sulfur separation flotation is beneficial to the improvement of copper concentrate grade. After a copper, lead , and zinc sulfide ore is compared by multiple schemes, copper-lead preferential flotation is used to obtain a copper-lead mixed concentrate, and a copper-lead separation scheme is implemented with a water glass combination inhibitor to achieve effective copper-lead separation. Get better flotation indicators. Through the - coarse, two sweep and three fine and medium ore sequence return process, water glass + sodium sulfite + CMC as an inhibitor, with butyl ammonium black medicine and ethyl xanthate as a collector , can be from 6.15% Cu, 40.20% Pb copper-lead mixed concentrate, closed-circuit test to obtain copper concentrate containing Cu 21.35%, Pb 6.48% and Cu recovery rate of 92.24%, and lead concentrate containing Pb 52.28% Cu 0.65% and Pb recovery rate of 95.47% . A copper-lead mixed concentrate in Guangdong is difficult to separate by conventional methods. In order to achieve the purpose of separating copper-lead, the test uses high-frequency vibrating fine screening, first classifying the mixed concentrate, and then performing a shaker on the +0.088mm sieve. Re-election; for -0.088mm sieve under the grade, with CMC, sodium sulfite and water glass mixture as inhibitor, Z-200 as collector, lead-free float copper. The small test results obtained a copper concentrate containing 24.15% of Cu and 3.68% of Pb and a lead concentrate containing 63.70% of Pb and 1.90% of Cu. Industrial test results: copper concentrate contains 2.235% Cu and 4.02% Pb; lead concentrate contains 60.31% Pb and 2.79% Cu.
