摘要
通过筛分试验和浮沉试验研究了砷在煤不同粒度级和不同密度级中的分布规律,并采用重液重选试验和分步释放浮选试验探究了重选和浮选对煤中砷的脱除效果。结果表明重选和浮选对于煤中砷的脱除都有较好的效果。
The distribution of arsenic in coal with different particle sizes and density fractions was studied by screening test and float-and-sink test. Gravity separation by heavy medium and flotation test by progressive release were used to research their effects on the removal of arsenic.Results show that both of the gravity separation and the flotation test have a satisfied effect on the removal of arsenic in coal.
