Abstract

The present invention discloses inflated metallurgical floatation process and apparatus, and features the completely covered microbubble inflating in the self balanced water separated microbubble generating and inflating mode. The apparatus includes a main machine, a bubble overflowing system, a microbubble generating separator, a microbubble generating system, an automatic mineral slurry regulating mechanism to control the liquid level, etc. Inside the floatation column, leaching tank and oxidation tank, great amount of microbubbles are generated in the bottom and flown in the opposite direction to the falling mineral slurry so as to raise the stirring effect, form stable floating bubble layer, speed oxygen dissolution, increase oxygen utilizing rate, enhance oxidizing leaching and raise floatation recovering rate.

Description

technical field

[0001] The present invention relates to a new micro-bubble aeration process of three-impeller agitation flotation column / leaching tank / oxidation tank, specifically a new aeration process and special equipment for metallurgical dressing flotation Column / leaching tank / oxidation tank) for microbubble aeration, which belongs to metallurgical technology. Background technique

[0002] At present, with the expansion and sharp increase of mineral development and utilization, the cut-off grade of useful minerals has decreased. In order to obtain more useful minerals, the scale of ore dressing plants has become larger and larger. However, no major improvements and breakthroughs have been made in terms of stirring the pulp and aeration methods. The effective volume of a single machine cannot keep up with the development needs, the flotation effect is not good, and the power consumption is large. For example, the inflating method of the leaching tank / oxidation tank in t...
