重庆南川铝土矿床矿石特征及工业利用性能评价

Chongqing Nanchuan bauxite ore characteristics and industrial utilization performance evaluation

重庆南川地区铝土矿资源丰富,该区铝土矿属古风化壳沉积改造型矿床,矿区内构造发育,矿体呈层状、似层状赋存于二叠系下统梁山组。矿石自然类型主要有致密状和土状铝土矿,主要矿石矿物为硬水铝石,其Al2O3含量一般在40%-75%之间,具有较高的工业利用价值,是重庆市优势矿产资源之一。本文以南川铝土矿为例分析说明该类矿床矿石特征及工业利用性能评价,以期为铝土矿床的勘查及开采提供理论依据。

Nanchuan District,Chongqing is rich in bauxite resources,the bauxite is a weathering crust deposition change other ores,mining area tectonic development.The ore body is stratiform,stratoid occurrence in the Permian system of Liangshan formation.The natural types of ores are mainly dense type and soil type bauxite,the main ore minerals are diaspore,the A1203 content of general between 40%to 75%,with higher utilization value in industry,Chongqing superiority mineral resources.This paper in Nanchuan bauxite as an example analysis illustrate the ore characteristics and industrial use of performance evaluation,in order to bauxite deposit prospecting and mining to provide a theoretical basis.
