The purpose and task of the feasibility study is based on the project proposal approved by the higher authorities. The feasibility study is a scientific analysis method to evaluate whether the construction project is technically and economically feasible. It is an important work in the early stage of design. Its purpose is to confirm the comprehensive effect of project investment through in-depth technical and economic argumentation, and provide a reliable basis for the correct decision-making of construction projects. The approved feasibility study report is the basis for determining the construction project and preparing the design documents. The basic task beneficiation plant construction feasibility study of the construction is a matter of principle, such as resources, the scale of construction, the principles of the process, the main equipment, products, solutions, market demand and address, external conditions, infrastructure investment, construction progress, economic effects, The ability to compete and analyze and demonstrate, so as to conclude whether the concentrator is constructed or not.
Feasibility study content
1. The basis and scope of the feasibility study work, the background of the construction project, the necessity of construction and the economic significance.
2. Research on the construction scale and product plan, and recommend the best plan; forecast the demand, price, sales and other conditions of the product.
3. Site selection and site plan comparison ((Several large ore dressing plants with complex site conditions should be carried out separately before the feasibility study).
4. Construction project content, main design plans and external conditions: (1) project composition; (2) resource and mining ore supply; (3); comparison of process flow and major equipment selection schemes and recommendations (introduction of technology or equipment) Further explain the necessity of introduction, the possibility of using foreign capital and the ability to repay; the expansion and expansion project should explain the utilization of the original fixed assets); (4); external conditions (external transportation, water supply, power supply, fuel and production) (5) the initial selection of the civil construction structure; (6) the preliminary selection of the public facilities and the mode of transportation within the plant; (7) the preliminary selection of the general layout plan of the whole plant.
5. The idea of ​​enterprise organization, labor quota and personnel training.
6. Suggestions for the construction cycle and implementation progress.
7. Investment estimate and capital financing.
8. Predict the impact of construction projects on the environment, and propose a preliminary plan for environmental protection and “three wastes†governance.
9. Analysis of economic effects and social benefits. It is necessary not only to calculate the economic effects of the concentrator itself, but also to calculate the macroscopic effect on the national economy (generally, mining, selection, and smelting joint venture calculations to the smelting process).
10. Provide traffic location map, overall layout plan, plant floor plan, process flow chart, process building system map, power supply and water supply system map.
11. Ask questions and suggestions.
Third, the content of the mineral processing profession in the feasibility study
(1) Briefly describe the mineralogical research of mineral deposits and ore types and ores;
(2) Briefly describe the mine supply conditions;
(3) Briefly and evaluate the beneficiation test;
(4); determine or participate in determining the construction scale and product plan;
(5) According to the beneficiation test and other materials, determine the process flow, indicators, working system and the specifications and number of main beneficiation process equipment through the comparison of the plan;
(6) Performing the layout of the process plant and the rough configuration of the equipment;
(7)) Initially determine the mechanization and automation level of the production process and auxiliary facilities items (such as laboratories, laboratories, technical checkpoints, pharmaceutical storage and preparation rooms, etc.);
(8) Propose the power and main material consumption indicators, estimate the investment and labor quota, estimate the investment and labor quota;
(9); drawing process flow chart and process building system diagram;
(10); presenting problems and suggestions.
