Embodiment 1
[0023] Embodiment 1: a kind of microwave roasting pretreatment graphite ore strengthened flotation purification method (see figure 1 ),Specific steps are as follows:
[0024] (1) The low-grade fine-scale graphite ore is crushed to a particle size of 0.83-1.7mm to obtain graphite ore particle A, and graphite ore particle A is pretreated by microwave roasting for 5 minutes to obtain graphite ore particle B; wherein the fixed carbon of low-grade fine-scale graphite ore The content is 5.63%, the main components of impurities are oxides of elements such as Fe, Al, Ca, Mg, Si, etc., and the water content is below 1%;
[0025] (2) step (1) graphite ore particle B is carried out wet grinding treatment to particle size not more than 0.075mm and accounts for 86% to obtain flotation graphite ore slurry;
[0026] (3) Step (2) Add 90g / t foaming agent A1 (No. 2 oil), 360g / t collector A2 (kerosene), 1000g / t regulator A3 (sodium silicate) in the flotation graphite pulp Sweeping, adding 45g / ...
