Molybdenum ore dressing plant management and control integration

Posted on

In recent years, due to the rapid development of computer, network, communication technology, some mining countries, such as the country of the United States, South Africa, Australia, Canada, Finland, Chile and other large and medium beneficiation plant, automatic control technology applications range from dehydration to crushing For each mineral processing operation, the measurement and control parameters include the grade, particle size and concentration of the minerals at each stage, as well as the state parameters of the various equipments from the crusher to the thickener. In the control plan, it also develops from the single-parameter, single-machine, single-segment control to the whole process, the whole plant, the whole plant-wide multi-level control and the integration of management and control. New domestic metal mines widespread introduction of Outokumpu size detector and pulp-line fluorescence analyzer, to achieve the fineness of grinding and flotation grade automatic control and online testing.

In recent years, mine production automation has developed rapidly in China. One of the effective ways for mining enterprises to improve product quality, improve comprehensive utilization of resources, increase production capacity, achieve efficiency and energy conservation, and improve competitiveness in the international market is to integrate management and control.

Wushan copper- molybdenum mine adopts large-scale open-pit mining, advanced SABC beneficiation process and tailings paste transportation process. The design and application of production monitoring system plays an important role in improving production efficiency, energy saving and consumption reduction. The production process of the Wushan copper-molybdenum ore dressing plant includes crushing, coarse ore yard, belt transmission and metering, sampling analysis, grinding (including feeding, water supply, concentration control), flotation, selection, flow detection, and elemental content. Analysis, concentrate measurement and other processes. Each process is equipped with corresponding equipment and control system. The technical indicators, production data and control parameters of each process in the production process are related to each other, mutually restrict and influence each other, and it is a continuous process type production process. Since the automatic control system (DCS, PLC, smart meter, etc.) independently configured according to the process or equipment is basically in an independent control state and cannot be centrally monitored, it is necessary to centrally monitor the entire production control process by constructing a production monitoring system. The production monitoring system is a collection of production information. The system helps the production management personnel to deal with emergencies in a timely manner by collecting various real-time data in the production control process, realizing two-way communication between the production planning layer and the production control layer, and quickly responding to the processing. result. The production process monitoring system uses the ideas and methods of system integration, adopts today's advanced computer technology, network technology, database technology, automatic control technology and field bus and many other technologies, and establishes production management and basic automation in accordance with the modern enterprise production management mode. The comprehensive system integrates and optimizes the real-time data and production management information of the entire production process of the enterprise, helping the enterprise to optimize the overall production and operation process.

Wushan Copper-Molybdenum Mine successfully implemented the integrated management and control system, through the direct data exchange with the basic automation system, to obtain the basic production data, make full use of computer information technology and data warehouse technology, process and release the data, and provide each A kind of data analysis tool, which is convenient for enterprise managers to understand mine real-time production information and adjust production without being restricted by geographical restrictions.
