Embodiment Construction

[0021] figure 1 and figure 2 Shown is an embodiment of a pyrite flotation process based on a carbon dioxide atmosphere in the present invention. Such as figure 1 As shown, a gas-tight cover 2 is arranged in the outer space of the self-priming flotation device 1 (flotation machine or flotation column) to form a flotation sealed cabin 3, CO 2 The compensation gas source 4 is connected to the flotation sealing chamber 3 , and the gas sealing cover 2 is provided with a transparent observation window 5 corresponding to the flotation machine 1 .

[0022] The air pressure in the flotation sealed cabin 3 is 1 atmospheric pressure so that the air pressure inside and outside the flotation sealed cabin is the same, and the purity of carbon dioxide is not less than 98.0% (can be monitored by a gas online monitor); 2 Compensation gas source 4 adopts liquefied carbon dioxide, uses a pressure reducing valve and a flow meter, and uses a pulp flow meter at a rate of 0.125Kg / m 3 Compensate...

Abstract

The invention discloses a pyrite flotation process method based on a carbon dioxide atmosphere. A gas sealing cover is arranged in the external space of a self-priming flotation device to form a flotation sealed cabin. 2 The compensation gas source is connected to the flotation sealed cabin; the air pressure in the flotation sealed cabin is 1 atmosphere so that the air pressure inside and outside the flotation sealed cabin is the same, and the purity of carbon dioxide is not less than 98.0%; Flotation is carried out in the flotation sealed chamber, and the amount of collector is 100-115g / t. The present invention uses carbon dioxide instead of air as the gas source and atmosphere of froth flotation, realizes the reduction of the dosage of flotation agents, and significantly improves the flotation index of pyrite, which is of great importance to the economic benefits of mineral processing enterprises and the control of environmental pollution. significance.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a pyrite flotation process. Background technique [0002] With the rapid development of productivity levels and social activities, environmental protection has become a global concern and emphasis. How to reduce the pollution and harm to the environment is the main task that enterprises need to face in production and people's life. [0003] In mineral processing production, the flotation process requires the use of a large amount of chemicals, which also brings about air pollution and tailings water pollution. great difficulties and heavy burdens. Therefore, how to effectively reduce the dosage of flotation reagents and at the same time realize the improvement of mineral processing indicators is of great significance to the economic benefits of mineral processing enterprises and the control and protection of environmental pollution. Contents of the invention [00...
