摘要
赫章叶腊石矿产于下二叠统梁山组第一段(P_1L^1),矿体呈层状与上下岩层产状一致.规模较大,矿石中叶腊石含量在80%以上,呈灰色块状,Al_2O_3含量大于25%,原矿耐火度在1700℃左右。矿石含铁较高是其缺陷,但只要经简单的洗选处理即可成为很好的耐火材料和陶瓷原料等。
Hezhang pyrophyllite ore yields in the first section of Liangshan formation of Lower Permian. The ore- body takes the shape of layers and is in accordance with the upper and lower rock layer occurrances, with the scale larger. The pyrophyllite-bearing quantity in ore-stone is above 85% and the pyrophyllite is in the shape of grey mass. The Al2O3 -bearing quantity is more than 25% , and the refractory degree of original ores is adout 1700C The higher Fe-bearing quantity of ore-stone is a defect, but the ore-stone can be used as a better refractory material and a ceramics raw material, etc. only through simple washing and choosing.
