摘要
针对棋盘井选煤厂浮选工艺不完善、浮选精煤灰分偏高的问题,基于生产现状分析,对二次浮选工艺进行改造。在对该选煤厂浮选工艺完善后,浮选精煤产率提高15个百分点,浮选精煤灰分能够控制在要求的范围内,经济效益显著。
Imperfection of flotation circuit and considerably high ash of flotation concentrate are the problems confronted by the plant. Following an analysis of the present status,a renovation work is made of the secondary flotation process. After upgrading of the flotation circuit,the yield of concentrate has seen a rise by 15 percentage points while the ash of the concentrate is controlled within the specified limit.This has brought forth remarkable economic benefits.
