The invention provides a molybdenum concentrate decarburization agent and a process for reducing carbon content of molybdenum concentrate. The molybdenum concentrate decarburization agent is preparedfrom the following components in parts by weight: 20-25 parts of sodium dodecyl benzene sulfonate, 2-5 parts of phosphate, 1-2 parts of diethanolamine, and 1-2 parts of a dispersant. The molybdenum concentrate decarbonizing agent can be used for reducing the carbon content of the molybdenum concentrate; in the process for reducing the carbon content of the molybdenum concentrate, the molybdenum concentrate decarbonizing agent is prepared into feed liquid, through the methods of ultrasonic treatment, concentration and filter pressing, the decarbonizing rate of the molybdenum concentrate can reach 75% or more, and the molybdenum concentrate with the carbon content less than 0.7% can be continuously and steadily produced; dust raising and environmental pollution are avoided, and environmentalprotection is facilitated; and production energy consumption is low, and resources are saved.
Description
technical field [0001] The invention relates to the field of ore dressing, in particular to a molybdenum concentrate decarburizer and a process for reducing the carbon content of the molybdenum concentrate. Background technique [0002] Molybdenum Concentrate MoS 2 It is lead gray, similar to graphite, with metallic luster. It belongs to the hexagonal crystal system. The crystal is often in the shape of hexagonal flakes, and the bottom surface often has patterns. It is soft and slippery, and the flakes are thin and flexible. Molybdenum concentrate can be used to produce ferromolybdenum alloy, metal molybdenum, calcium molybdate, ammonium molybdate, lubricants, etc. Flotation is the main method of beneficiation of molybdenum concentrate. The flotation process of molybdenum concentrate often adopts a process of coarse grinding and roughing, coarse concentrate regrinding and re-selection. The carbon content of the molybdenum concentrate has an important impact, which often le...
