Mine design considerations:

First, the basic construction procedure is a summary of China's basic construction practice for many years. It is an objective and regular response and an important guarantee for the smooth progress of basic construction. Therefore, beneficiation plant design must be carried out according to the basic construction procedures prescribed by the State, the conditions required for the design must have, must complete basic data required for the design, content and design documents must comply with the appropriate depth design phase.

2. Before the design, it is necessary to strengthen the on-site investigation and experimental research, fully occupy the basic data needed for the design, and carefully analyze the construction conditions; the design should solve the various problems in a realistic manner; after the design, it should cooperate with the construction, complete the production, and make the design summary. jobs.

Third, the design principles and design plans should be determined in accordance with the guidelines and relevant provisions of the national industrial construction, and implement relevant standards, procedures and norms.

Fourth, the introduction of foreign advanced technology should be based on accelerating the improvement of China's science and technology level and increasing China's ability to self-reliance, must pay attention to economic effects, according to needs and possibilities, do a feasibility study in advance to determine whether to introduce. At the same time, attention should be paid to digestion, mastery, transplantation and development of imported technologies.

Fifth, the design of the concentrator should have access to the best technical and economic indicators and to maximize the economic benefits, and construction funds can be recovered as soon as possible and quickly turnaround.

Sixth, the design process and indicators should have certain advancement and reliability. Mineral resources should be used as comprehensively as possible. If the recovery of certain useful components in the ore is difficult or economically insufficient under current technical conditions, the storage measures should be considered and experimental research should be actively carried out for future use. The product plan should reasonably determine the concentrate grade and recovery rate to achieve high quality and high yield.

7. According to the production technology level of domestic and foreign machinery manufacturing industry, the selection of advanced and high-efficiency process equipment, especially the equipment with low energy consumption, makes the concentrating plant have a higher level of mechanization. The level of automation must be in line with national conditions, and it must reflect the development direction.

The typical factory that can represent the advanced level of the country must also consider the specific situation of China's current automation design, operation, maintenance and management level.

8. The design of the ore dressing plant must pay attention to reduce energy consumption. For example, it is necessary to create conditions for the slurry self-flow transportation, avoid and reduce the reverse transportation of materials, strengthen the pre-selection operation, reduce the grinding grain size, and try to achieve coarse grain tailing in the grinding operation. Increase equipment load rate,

Increase the concentration of the tailings slurry and so on. Each process should be equipped with energy consumption meters for easy inspection.

IX. Equipped with necessary maintenance sites, equipment and maintenance facilities to ensure that the equipment can operate normally and continuously.

10. In the design of the concentrator, the construction conditions and strength of the construction area should be considered to ensure that the construction of the concentrator can be carried out as planned; the equipment and building components should be standardized and standardized in order to shorten the construction time and speed up the construction. .

XI, when the concentrator complex terrain located in remote areas, the construction of the railway is very difficult to concentrate in larger quantities and long distance transport and the possibility of pipeline transportation should be a priority.

12. For the construction of new concentrating plants, especially large-scale concentrating plants for underground mining and mining, it is necessary to seriously study the possibility of construction or phased construction, and strive to achieve less investment, faster construction, higher returns, and give full play to the investment results.

XIII. Correctly handle the contradiction between industry and agriculture in terms of land use and water use. In the basic construction, land must be saved. Wasteland and inferior land should be used as much as possible. It should not occupy or occupy less cultivated land, avoid water competition with agriculture, and not hinder the construction of farmland water conservancy. Under the possible conditions, it is appropriate to reclaim land and expand agriculture. Retreat area.

14. The concentrator is an intermediate link between the mine and the metallurgical plant (or raw material mining and finished product utilization). Therefore, the designed concentrator should be in terms of working system, production capacity, process flow, mining mode, processing equipment, etc. Compatible with the production and transportation conditions of the stope, and the requirements of the metallurgical plant (or finished product utilization department) in terms of product plan and finished product storage and transportation.

15. The water supply, power supply, transportation, material supply, repair and distribution services, and service utilities of the concentrator should be coordinated with other local businesses as much as possible.

16. The equipment configuration of the concentrator must meet the requirements of the process flow. The flexibility of the process must be considered. The stress should be compact and reasonable, and transported as far as possible. The production plant should have sufficient operating space and transportation facilities to ensure the smooth flow of materials. The area and volume of non-productive facilities should be appropriate.

17. The designed ore dressing plant shall have the necessary technical safety and labor protection measures. It is necessary to pay attention to the protection of the environment, especially to improve the process, to prevent dust, poisons, waste water, waste gas, waste slag, radioactive and other harmful substances and noise pollution to the environment, and comprehensive management, so that the design meets the standards set by the state.
