Abstract
The invention discloses a fluorite floatation process, which comprises the following steps of (1) preparing a raw material: taking low-quality fluorite ores as the raw material, and taking linoleic acid, peanut oil and sodium dodecyl sulfate as a collecting agent, wherein the collecting agent is obtained by fully and uniformly mixing the linoleic acid, the peanut oil and the sodium dodecyl sulfate; (2) grinding the raw material into powder: grinding the low-quality fluorite ores to obtain powdery fluorite in an ore grinding machine, wherein the granularity of the powdery fluorite is 200 meshes; (3) performing floatation: adding water in an amount which is 4 times the weight of the powdery fluorite into the powdery fluorite to obtain slurry, sequentially adding sulfuric acid, water glass, hydrofluoric acid and the collecting agent, and performing floatation for three times to obtain floated fluorite, wherein based on the total weight of 100 tons of the slurry, 150 to 350 grams of sulfuric acid is added, 1,000 to 1,500 grams of water glass is added, 450 to 600 grams of hydrofluoric acid is added, and 500 to 750 grams of collecting agent is added.
