How to Choose Chunks of Fluorite Ore
How to Choose Chunks of Fluorite Ore
Quality fluorite mine in the chemical and metallurgical field has very important applications, but most of the native fluorite ore contain other impurities can not reach grade industrial production, the need for beneficiation and purification. Chunks of high-quality fluorite ore is of high quality metallurgical cosolvent, but it should be chunks of fluorite ore how to choose it?According to statistics, 90% of metallurgical fluorite ore chunks are available through the gravity separation of the method, and the other 10% comes from the artificial hand-selected. From this we can know, bulk pick fluorite ore, mainly through the gravity separation of the method can also be complemented by hand-selected method.
After the actual production, due to the fluorite mining occurred during different size fractions fluorite mine, the need for screening, crushing and other processes into the washing process. Under normal circumstances 0-30mm fluorite ore can all be gravity separated by washing and purification methods, commonly used equipment is gravity separation jig, jig can be carried out in accordance with the proportion of mineral ore and gangue difference between thus sorted larger proportion of fluorite ore and a smaller proportion of waste rock, but jigger election fluorite ore more stringent requirements on the grain size, usually need to set up the screening process before grading jigger of 0-30mm grain grade fluorite ore into several different size fractions, and then choose a different jigging machine washing and purification, and ultimately get the specific size fractions of concentrates and tailings. For more than 30mm of fluorite ore will need to be hand-selected by sorting method, which is observed fluorite and gangue differences in color, grain shape through the eyes, and then pick out the chunks of firefly quality hand picked by artificial means quarry.
In fact, chunks of fluorite ore concentrate is hand-selected by France and the re-election of two of the most short-answer method to get the dressing, hand-selected sorting method can fluorite large blocks, but labor-intensive, beneficiation index is not stable, only suitable for small-scale production. Gravity separation beneficiation are stable, beneficiation efficiency is higher, is the main method used in metallurgy fluorite ore production.
