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.
Second, the feasibility study content 1. The basis and scope of the feasibility study work, the background of the construction project, the necessity of construction and 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) Resources and mining ore supply;
(3) Comparison of process flow and major equipment selection schemes and recommendations (introduction of technology or equipment should further explain the necessity of introduction, the possibility of using foreign capital and repayment ability; the expansion and expansion project should explain the utilization of the original fixed assets) ;
(4) Demonstration of external conditions (external transportation, water supply, power supply, fuel, and supply of other materials required for production);
(5) Preliminary selection of civil structural forms;
(6) Preliminary selection of utilities and in-plant modes of transport;
(7) Preliminary selection of the overall 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 concentrating plant itself, but also to calculate the macroscopic effect on the national economy (generally, the mining, selection, and smelting joint ventures are calculated to the smelting process). [next]
10 Provide traffic location map, overall layout plan, plant general plan, process flow chart, process building system map, power supply and water supply system map.
11 raised problems and suggestions.
3. The work content of the ore dressing profession in the feasibility study (1) Briefly describe the mineralogy of the deposit and ore type and ore;
(2) Briefly describe the mine supply conditions;
(3) Briefly and evaluate the beneficiation test;
(4) Identify or participate in determining the construction scale and product plan;
(5) According to the beneficiation test and other materials, the process flow, indicators, working system and main process equipment specifications and number of units are initially determined through comparison of the plans;
(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 projects (such as laboratories, laboratories, technical checkpoints, drug storage and preparation rooms, etc.);
(8) Propose the power and main material consumption indicators, estimate the investment and labor quota;
(9) Drawing a process flow chart and a process building system diagram;
(10) Propose problems and suggestions.
Concentrator feasibility study
I. Purpose and Task of Feasibility Study The basis for the feasibility study is 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 also the basis for determining the construction project and preparing the design documents.
