大型露天金矿组合生产规模论证分析
发布时间：2018-12-16 05:40
【摘要】：针对露天矿采选生产中不同类型及品位矿石所产生的经济效益的差异,选择了堆浸和全泥氰化两种选矿工艺组合生产。确定了经济比较指标,采用多项式回归分析法预测生产成本,建立了露天矿生产规模论证模型。通过对静态、动态经济比较分析,从净现值、内部收益率、生产现状等因素综合考虑,确定了两种选矿工艺的最优组合规模,为矿山生产提供了理论指导和充分的决策依据。
[Abstract]:In view of the difference of economic benefit between different types and grade ores in opencast mining and dressing production, the combined production of heap leaching and total mud cyanidation was selected. The economic comparison index is determined, the production cost is predicted by polynomial regression analysis, and the scale demonstration model of open pit mine is established. Through the comparative analysis of static and dynamic economy, considering the factors such as net present value, internal rate of return and present situation of production, the optimal combined scale of the two mineral processing processes is determined, which provides theoretical guidance and sufficient decision basis for mine production.
