查询词典 pyrite

In addition, high-resolution time-of-flight secondary ion mass spectrometry was used to study the chemical composition of various pyrite forms in the No.9 coal seam (St,d = 3.46%) from the Wuda Coalfield. These include bacteriogenic, framboidal, massive, cell-filling, fracture-filling, and nodular pyrites.

The flotation effect of BET was compared with that of the commonly used reagents GF and FS202. The result shows that although the usage of BET is only 1/10 and 1/100 of GF and FS202 respectively, the collectability and selectivity for pyrite and coal gangue is obviously better than that of using GF and FS202. In addition, it will not be influen...

结果表明：尽管 BET的用量分别是 GF，FS2 0 2用量的 1 /1 0和 1 /1 0 0 ，但对黄铁矿、煤矸石等捕收性和选择性明显优于 GF，FS2 0 2 ，且不受 p H条件的影响；与其它 3种同系物(AET，DET，HET)在脱硫降灰方面综合比较表明，BET的效果最好，具有用量少、选择性强等优点，是一种应用前景良好的煤炭浮选药剂。
