Flotation Technology Decided by a Bubble Flotation Separator

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) February 14, 2012 -- Flotation technology is the most important way to observe a bubble flotation separator, and according to changes in foam flotation to determine the effect good or bad. Experienced workers from the flotation separator operation the apparent bubble phenomenon observed the changes, we can determine the reasons for any changes to make timely adjustments in the flotation process to ensure optimal conditions.

Workers can correctly adjust the flotation reagent dosage, the amount of concentrate were scraped off and the circulation rate in the mine, first of all depends on his quality of flotation froth appearance of the right to determine the degree of the observation, the ability to judge mainly from constant and careful summary of operating experience gained. The appearance of foam, including foam flotation actual situation, size, color, luster, shape, thickness, strength, mobility, audio, and other phenomena that are mainly of minerals from the bubble surface attachment type, quantity, size, color, luster, density, the amount of foaming agent how much the decision.

1, large and small bubbles: bubbles the size of the foam layer surface, often with the ore properties, reagent and flotation of the region and change;

2, the virtual and real bubble: the bubble surface attachment of mineral particles and more dense, bubble is real. Mineral particles attached to the bubble surface few and thin, the bubble is true, high grade ore, the appropriate amount of reagent, the bubble is real, inhibitors over the collector is too small bubble will become virtual.

3, color: color of sweeping electoral deeper fossil plankton, the greater the loss of metal, crude minerals selected areas darker zooplankton, the better the quality concentrate


4, Luster: roughing flotation sulfide minerals, a good selection of area bubble mineralization, its metallic luster strong, sweeping electoral bubble mineralization is poor, showing the shiny glass of water film. If the sweep appears semi-metallic luster election bubble, indicating that the metal loses much;

5, thick and thin: the thickness of foam layer mainly the amount of foaming agent, air bubbles between the degree of mineralization, foaming agents and more high-grade ore, the concentration of large, well mineralized, generally thick foam layer, and vice versa relatively thin, floating ore particles are too thick, it is difficult to form thick foam layer, the selection of low surface area of ​​slurry, foam thickness, high grade concentrate, the slurry surface to maintain the high electoral sweep was timely scrapings floating minerals, foam layer thin, the high recovery rate .

6, profile: The moderate hydrophobicity of mineral particles in the slurry surface mineralization of the bubble is formed, sufficient water, the outline of each bubble are relatively clear, the surface of the bubble to stay longer in the pulp, minerals hydrophobic large, cell wall dry incomplete, the fuzzy outline of the bubbles;

7, sound: bubble was blown foam scraper groove issued a 'rustling' sound, often contains large amounts of foam larger proportion of coarser mineral.

8, the brittle and viscous: the brittle foam is too much, poor stability, easy to break, sometimes scraping does not come out, on the contrary, foam viscosity is too large, too much stability, flotation would 'run tanks' and undermine the normal flotation process, resulting in concentrate transport difficulties, excessive foaming agents, oil or minerals fall into a large number of mines in the mud and sulfuric acid soluble lead salts, the foam can be too stable;
