Abstract

The raw coal of Ping Coal No.1 Mine is highly muddied and extremely difficult to separate, which is generally sold as power coal.In order to improve the competitiveness of the market, we tried to convert it into coking coal through coal preparation, We explored and solved the problem of high circulating water concentration caused by high sludge and deterioration of flotation index due to high ash and fine sludge, and successfully converted it into coking coal, which not only improved the economic value of the raw coal, but also improved the competitiveness of the product and the economic benefits of the enterprise are improved.
