Feed from the processing plant effluent stream is directed to the UFR sump. The slurry is then pumped at a relatively high pressure to multiple Hydrocyclones using a McLanahan rubber lined Pump. The Hydrocyclones recover most of the +400 mesh (38µm) fractions as partially dewatered underflow, which is in turn directed to the Dewatering Screen.
When coals are burned, leached and washed, sulfur will be released in the form of sulfide and H 2 S, which then react with O 2, water and other substances to change into vitriol, and in some places it may form acid rain. And they will impact water environment, acidify the soil and do great harm to plants and human health.
