Problems solved by technology

If the easily floating siliceous minerals cannot be effectively removed, the subsequent floating sulfur will also be difficult to suppress due to the easy floating siliceous minerals, so that the sulfur concentrate obtained by flotation will contain high silicon content and the quality will not meet the requirements
Can not effectively comprehensively recover copper, sulfur and other minerals in the ore

Embodiment Construction

[0011] Below with embodiment the present invention is described in further detail:

[0012] The ore of the embodiment is a high-sulfur copper ore containing higher siliceous minerals such as talc, and the metal sulfide minerals mainly include magnetite, pyrite, chalcopyrite, etc., and its raw ore grade is: copper 0.36%, iron 38.56% , sulfur 28.49%.

[0013] Steps:

[0014] Firstly, the ore is ground to -0.074mm, accounting for 65%, so that the copper and sulfur minerals are fully dissociated, and the magnetite is separated by magnetic separation. After magnetic separation, the non-magnetic ore pulp is concentrated to a pulp concentration of 35%. According to the primary roughing, secondary beneficiation, and primary sweeping beneficiation process, mixed flotation of chalcopyrite and easy-to-float siliceous minerals, the dosage of the agent is: coarse For selection, add 75g / t of No. 200, add 25g / t of butylammonium black medicine, add 50g / t of No. 2 oil; scan, add 30g / t of No....

Abstract

The invention relates to a copper-separating process of high-sulfur copper ore containing higher silicate minerals of speckstone and the like. The process comprises the following steps of: using solvent naphtha No. 200 and aerofloat sodium as a collector, oil No. 2 as a foaming agent and sodium sulfite as an inhibitor; carrying out bulk floatation on chalcopyrite and easily-floating silicate minerals; adding aluminum sulfate and ferrous sulfate for inhibiting the obtained copper-silicon mixed concentrate ; and re-separating and recovering the chalcopyrite by using a shaker. By the provided copper-separating process, copper ore in ore can be effectively recovered, the easily-floating silicate minerals are floated in the copper-separating process, and the influence of the silicate minerals of speckstone and the like on the subsequent floatation and recovery of sulfurous iron ore is eliminated.

Description

1. Technical field [0001] The invention relates to a beneficiation technology, in particular to a copper beneficiation process of high-sulfur copper ore containing talc and other siliceous minerals. 2. Background technology [0002] At present, for the comprehensive recovery of copper and sulfur minerals in high-sulfur copper ores, the beneficiation process of first floating copper and then floating sulfur is usually adopted. However, when encountering ores with high siliceous minerals such as talc, talc and other siliceous minerals are easy to float and difficult to suppress when floating copper, so that the copper concentrate obtained by flotation contains high silicon, reducing the grade of copper, and the quality reaches Less than required. If the easily floating siliceous minerals cannot be effectively removed, the subsequent floating sulfur will also be difficult to suppress due to the easy floating siliceous minerals, so that the sulfur concentrate obtained by flotat...
