摘要
当前,我国的矿业形势发生了根本性的变化,首先是选矿技术、选矿设备、选矿工艺技术改造取得了重大突破,工艺装备水平得到跨越式提升,绝大部分选矿厂的选矿作业流程都进行了优化改造;其次,新建矿山数量大幅度增加,新建矿山选矿厂的技术水平、装备水平和自动化控制水平都非常高;再次,复杂难选矿石的选矿技术取得了重大进展,精矿品位、品质得到大幅度提高,矿业经济取得了辉煌的成果,矿山企业的规模、效益同步增长,一条科技含量高、经济效益好、资源消耗低、环境污染少、人力资源优势得到充分发挥的新型工业化路子基本形成。
本课题旨在研究、选矿设备水平的现状,对今后几年铬矿石选矿厂的分布调整、选矿工艺技术和选矿设备的发展趋势进行展望。
因此,本课题对国内铬矿石选矿技术、装备、工程及生产具有重要参考价值。对矿产资源开发、选矿工程建设等具有参考价值。

ABSTRACT
At present, the mining situation in our country there has been a fundamental change, first of all, mineral processing technology, processing equipment, processing technology has made a major breakthrough in technology, technique and equipment to upgrade the level by leaps and bounds, the vast majority of the ore dressing ore dressing plant processes have been Optimization of the transformation; Secondly, a significant increase in the number of new mines, new mining concentrator technology, and automation equipment levels are very high level of control; again, plexity of refractory ore beneficiation technology has made significant progress, concentrate grade, quality has been substantial increase in mining economy has made brilliant achievements, the scale of mining enterprises, a simultaneous increase in efficiency, a high technological content, good economic returns, low resource consumption, less environmental pollution, human resources into full play the advantages of the basic formation of new-type industrialization road .
To study the issue of domestic chrome ore concentrator distribution, the level of mineral processing technology, the status quo level of mineral processing equipment to explore and prospect of the next few years the distribution of chromium ore concentrator adjustment, processing technology and the development trend of ore-dressing equipment, so , the subject of domestic chrome ore beneficiation
