2019-5-1 · 1. Introduction. Flotation is a treatment process of ores and with about two billion tonnes of floated crude ore per year it is one of the most important processes for the enrichment of valuable minerals (Yianatos, 2003).Fluorite (CaF 2) is separated by means of flotation from gangue particles such as barium sulphate (BaSO 4) and silica (SiO 2) is used for the synthesis of hydrogen fluoride ...
2020-7-1 · The micro-flotation tests of fluorite and calcite were carried out in an XFG flotation machine. The rotation speed was controlled at 1602 rpm. For each test, 2g of the pure mineral samples were added to 40 mL flotation cell and agitated to obtain the uniform slurry.
In this study, two new collectors for fluorite flotation DP-OMC-1033 (DP-I) and DP-OMC-1234 (DP-II) were tested and compared with oleic acid (OA), sodium oleate (SO) and potassium oleate (PO). According to fluorite grade and fluorite metallurgical recovery, the effect of each collector was determined, both in mechanical and pneumatic cell flotation.
Fluorite flotation process is applied for refractory fluorite with complicated properties such as high mud content, impurity containing, fine particle distribution etc. Our fluorite flotation process has many advantages including automatic controlling, high efficiency, safety, …
2019-11-13 · Fluorite flotation process is applied for refractory fluorite with complicated properties such as high mud content, impurity containing, fine particle distribution etc. Our fluorite flotation process has many advantages including automatic controlling, high …
2005-1-28 · Fluorite is an important raw material for metallurgical and chemical industries. The flotation with oxihydrilic collectors (sodium oleate etc.) is the main process of fluorite recovering from ores, and a considerable amount of study has been devoted to the physicochemical aspects of its flotation (Hanna and Somasundaran, 1976;
The main problem of fluorite flotation process is the separation from symbiotic gangue (quartz, calcite, barite, etc.). There is also the problem of separation from some sulfide, according to different condition, the flotation method is also different: For fluorite containing sulfide ore, it is common to surface the sulfide ore with xanthate ...
Having thus described our invention, what we desire to secure by Letters patent and hereby claim is 1. In a flotation process for the recovery of fluorite from clay-containing ores, the improvement which comprises, prior to carrying out conventional flotation, conditioning a flotation slurry by treating said slurry for a period of from about 1 to 10 minutes with from about 100 to 200 grams per ...
