The Yunnan Phosphorus Group’s Jinning Yellow Phosphorus Company, part of Yuntianhua, produced over 300 tons of phosphorus pentoxide in April 2014. Since the electricity production cost during the dry season is 0.1 yuan per kilowatt-hour higher than that during the wet season, it is expected that the facility will operate at full capacity once the wet season begins in June. 　　According to Zhang Yong, deputy manager of the Yellow Phosphorus Company, the company’s 4,000-ton/year phosphorus pentoxide production facility was completed at the end of 2013, after which a 72-hour chemical feeding trial run was carried out. During the trial production phase, the heat recovery rate reached 50%; the recovered heat was used to heat the pulp and reagents in Yunnan Phosphating’s 4.5 million tons per year flotation plant, which effectively increased the yield of phosphorus concentrate. It is estimated that this system can generate over 1,000 tons of steam per year.
