Parameters optimization of coal slime flotation in Xinglongzhuang coal preparation plant

To make the coal slime flotation parameters of Xinglongzhuang coal preparation plant in optimal condition,the coal sample from Xinglongzhuang was studied as the main research object,conducted the test of best floatation reagent choosing and dosage,also determined the best pulp density and dosing mode.Based on the best experiment conditions,the flotation speed test was carried out.The experimental results showed that when the collector selected is TDS,the dosage is 800 g/t,the foaming agent selected is HL-03 A,the dosage is 100 g/t,and added at one time,the flotation effect is better.Under the best experiment conditions,the yield of clean coal is 42.93%,ash content is 9.83%,and complete index of flotation is 42.48%,which meet the requirement of production.
