Mineral beneficiation process plant design is based on the main body, with other relevant professional assistance of the overall design. In the design process, we must solve a series of future mineral processing plant construction and production problems, including: 1) production process problems; 2) construction problems; 3) supply of raw materials, materials, water, power, labor; 4) finished products Sales; 5) transportation of raw materials and products; 6) construction of residential and cultural welfare facilities; 7) determination of site selection; 8) maintenance problems; 9) environmental protection and other issues. Therefore, the design of the concentrator is usually divided into the following parts. 1. The general part of the general and technical economics section should briefly and concisely discuss the main design basis, the conclusions of major design proposals, the comprehensive effects of enterprise construction, problems and suggestions, etc. The common problems of various professions such as scale, site, raw materials, fuel supply and products The program is also reviewed in the general section. The main section includes technical and economic comparison of design, labor capacity and labor productivity, infrastructure investment, working capital, product costs and profitability, investment loan repayment capacity, enterprise branch building effect and comprehensive technical and economic indicators. 2. Process part This is the main part of the design of the concentrator. These include the ore properties and ore supply conditions, the ore dressing test results and reviews, the beneficiation process and indicators used in the design, the selection and calculation of major equipment, the characteristics of the beneficiation equipment configuration, and the internal and external transportation. Auxiliary facilities, etc. 3. The general transport part includes the overall layout of the enterprise, the general layout of the industrial site, and the internal and external transportation of the enterprise. 4. The civil works include design plans for major buildings and structures, administrative and welfare facilities, staff residential area planning, and building maintenance. 5. Power, automation, and thermal power components include power, power transmission, lighting, and automated instrumentation. The thermal part includes industrial boiler rooms and diesel engine power stations. 6. Water supply and drainage, tailings and heating and ventilation parts include water sources, water supply systems and river diversions. The tailings facilities include tailings ponds and their structures, tailings conveying systems, accident tailings facilities, and treatment facilities for tailings water and concentrate overflow water. The heating and ventilation section includes the heating and ventilation system of the main production workshop, auxiliary production workshop and living welfare facilities and its main facilities. 7. The mechanical repair facilities include the composition of the electromechanical repair shop, the selection and installation of the main mechanical repair equipment. 8. Environmental protection includes treatment processes for wastewater, waste gas, waste slag, waste rock, tailings, etc. and noise and vibration prevention measures, evaluating the environmental background before the construction of the enterprise and the impact on the environment after construction, indicating the environmental protection management organization and environment of the concentrator Monitoring systems, means, main instruments and opinions of local environmental protection departments. 9. The estimates include estimates for the various projects of the concentrator, comprehensive estimates and general estimates.
Boride-based powders are commonly used in thermal spray applications due to their high hardness, wear resistance, and thermal stability.
