广西某银矿选矿流程精益化管理研究
|
摘要
矿山选矿阶段作为矿石的主要加工处理过程,是影响矿石精矿品位和矿山经济效益的重要因素,选矿流程管理不当会造成矿石精矿品位降低和矿山经济效益的流失。通过分析广西某银矿山选矿流程现状,运用鱼刺图分析法列举该流程面临的主要问题,并进一步利用解释结构模型ISM(Interpretive Structure Modeling)流程分析法找出瓶颈影响因素。模型分析结果表明,该银矿选矿流程存在的最主要问题是精益理念不强、现场管理不当和原矿石品位低,并针对模型分析结论提出该银矿选矿流程精益化管理建议。
With the deepening of supply-side structural adjustment of mining economy,the resource reserves are decreasing and the environmental protection requirements are becoming increasingly stringent. The traditional quantitative,technology-oriented mining production activities is adjusted to the level of technology and management mode innovation.The scientific management mode of mining and dressing production,mining rights,mineral products trading and other production value-added activities in the traditional mining industry is also constantly being innovated and optimized. As the main processing process of ore,the mineral dressing stage is an important factor that affects the grade of ore concentrate and the economic benefit of mine.Improper management of ore dressing process will lead to the decrease of ore concentrate grade and the loss of mine economic benefit.Lean management of mine beneficiation process is of great significance.The research object is the second largest independent silver mine in China. With more than 20 years of resource extraction and separation,and because located in the disputed area of the nature reserve,the mine is obviously restricted by reserves and environmental protection.The ore dressing production process is relative perfect and the scientific management mode is applied. In order to further find out the reasons for the loss of economic benefits of the mine,provide reference for the lean management of the mine beneficiation process,the mine dressing production process was selected as the research object. The process of ore dressing production was express by using flow chart,the problems existing in the process of ore dressing was solicited with Delphi method,then the main problems in this process were listed by fish-prick-graph analysis method.Interpretive Structure Modeling is further used to distinguish the influencing factors at different levels,and identify the bottleneck factors. The results show that,the low grade of raw ore and the improvement of tailings treatment will lead to the loss of benefit directly.Low efficiency of automatic operation and equipment aging degree will affect tailings treatment significantly.The main problem in the process is that the lean idea is not strong and the field management is not good. Based on the conclusion of model analysis,some suggestions on lean management of the silver ore dressing process are put forward. Firstly,constructing lean core ideaSecondly,carrying out the scientific field management method in practice.
