A molybdenum concentrate decarburizer and a process for reducing the carbon content of molybdenum concentrate

Abstract

The application provides a molybdenum concentrate decarburizer and a process for reducing the carbon content of the molybdenum concentrate. The molybdenum concentrate decarburizer molybdenum concentrate decarburizer provided by the present invention comprises, in parts by weight: 20-25 parts of sodium dodecylbenzenesulfonate; 2-5 parts of phosphate; 1-2 parts of diethanolamine ; 1-2 parts of dispersant. The molybdenum concentrate decarburizer provided by this application can be used to reduce the carbon content of molybdenum concentrate. In the process for reducing the carbon content of molybdenum concentrate provided by this application, the feed liquid prepared by the molybdenum concentrate decarburizer is used. The method of ultrasonic treatment, concentration and pressure filtration makes the carbon removal rate of molybdenum concentrate reach more than 75%, and can continuously and stably produce molybdenum concentrate with carbon content less than 0.7%. It avoids the problems of dust and environmental pollution, which is beneficial to Environmental protection; low production energy consumption, saving resources.

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...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the decarburization agent and decarburization process that are not specially used to reduce the carbon content in the molybdenum concentrate obtained by flotation in the prior art, and the environment caused by the drying step in the existing decarburization process. pollution and waste of resources, thereby providing a molybdenum concentrate decarburizer and a process for reducing the carbon content of molybdenum concentrate
