Flotation reagent plays an important role in flotation process. If the reagent consumption is too high, it will inevitably lead to the increase of flotation cost, so as to reduce the economic benefits of enterprises. Engineer Li of Hongxing machine beneficiation Research Institute has put forward several methods to solve the high consumption of flotation reagent in the flotation process. Xiaobian is here to borrow flowers and offer Buddha for your reference.

In the flotation process, the ore particles expand the particle floatability under the action of flotation reagent. The ore particles with good floatability float upward, overflow in the pulp, and then dehydrate and dry to obtain the finished product. In actual production, the flotation process of slime separation often has the phenomenon of high consumption of flotation reagent, which seriously affects the product quality. Taking slime separation as an example, this paper explains the causes and solutions of high consumption of flotation reagent.

1. There are many kinds of raw coal to be washed and frequent changes in washing, resulting in unstable flotation concentration.

Ensure that the floating concentration is controlled at 90g / l-100g / L. if there is a concentration that does not meet the requirements, timely record the type of raw coal and washing amount in case of change for later inspection. Master the raw coal washing in advance, determine a reasonable reagent system, adopt different flotation operations and different reagent addition ratios for raw coal of different mines.

2. The flotation operators lack the operation experience of various coal floatation.

A flotation operator training plan can be established to train flotation operators in theory and skills and improve the operation level of flotation operators.

3. The routine maintenance and cleaning of flotation equipment are not in place.

Clean the flotation machine and pulp preparer once a week, check the reagent atomization plate at any time, ensure the atomization effect of the reagent, save the consumption of the reagent, strengthen the inspection of the equipment, and timely report and repair the problems found in the flotation machine and pulp preparer.

More responsibility is more beautiful. If everyone can put this person's responsibility in his heart, why worry about the road ahead!
