探讨降低露天铝矿贫化和损失的途径

矿石的损失率与矿石的贫化率是矿山企业在生产管理中最要的两项指标，矿石的贫化率和损失率较高，是造成矿产资源浪费和制约矿山企业经济效益的突出问题。本文介绍了露天铝矿床的地质和开采概况，针对矿层和顶底板变化大的特点，探讨了在露天铝矿开采过程中降低贫化和损失的途径，提出了计算贫化率和损失率的方法，有助于矿山企业分析管理，提高矿山企业经济效益。

Discuss the Way of Reducing Aluminium Ore Dilution and Loss on Opencut Mining

The dilation rates and loss rates of mineral are two most important indexes in the management of mine enterprises.The higher dilation and loss rates can result in the waste of mine resources and restriction economic benefits of mine enterprises.In this article the auther introduce the geology and exploitation general situation of the opencut aluminium mine, In accordance with their special characteristic that the ore horizon and roof bottom are great changes,discuss the way of reducing ore dilution and loss on opencut aluminuim mining and advances the methods of accounting dilation and loss rates,it can controbute to the analysis and management,in.increase the economic benefit of mine enterprises.
