Mineral processing refers to the process of separating useful minerals from gangue minerals by gravity separation, flotation, magnetic separation, electrostatic separation and other methods after the ore is crushed and ground, and various symbiotic (associated) useful minerals are separated from each other as much as possible, and harmful impurities are removed or reduced to obtain raw materials required for smelting or other industries. The main purpose is to improve the grade and remove impurities to achieve high-grade concentrates that meet smelting standards. Among them, flotation is the most widely used mineral processing method, and almost all ores can be separated by flotation.
Mineral processing chemicals include various types (properties) and uses of special chemicals used in various processes of mineral processing technology, which are divided into collectors, frothers, adjusters, auxiliary agents and other mineral processing chemicals. They are mainly used in flotation mineral processing, and their industry development is closely related to the development of downstream mineral resources industries.
As a commonly used ore dressing method, my country has mastered relatively mature technology. Before the strong magnetic separation technology was available, my country's iron ore dressing mainly used positive flotation technology. This technical process is simple, and the reagents are cheap and easy to obtain. Its disadvantages are that the gangue minerals in the ore and the sludge in the flotation process will not only increase the amount of reagents used, but also make it difficult to dehydrate the concentrate.
The mineral structure of foreign iron ore is simpler than that of China. Cationic collectors are usually used for flotation, but cationic collectors have a large amount of foaming, and there are problems such as sticky foam and difficulty in defoaming, subsequent work is difficult to handle, and the cost of reagents is expensive.
my country mainly uses anionic reverse flotation technology to process iron ore. The advantage is that there is no need to worry about the harm of calcium ions in the slurry. The synergy between reagents is good, the recovery rate is high, and it has a strong adaptability to the complex changes in ore properties, and can obtain a higher concentrate grade. The disadvantage is that traditional ore dressing reagents need to heat the slurry, the selectivity is poor and the dosage is large, and there are many types of reagents and difficult configuration.
In general, the application of mineral processing agents has promoted the development of the mining industry and greatly improved the resource recovery rate of mineral resources. However, the pollution problem of flotation agents to the environment is a key factor that restricts their greater efficiency. With the continuous development and utilization of mineral resources, mineral resources have gradually shown characteristics such as "poor", "mixed" and "fine", and traditional mineral processing technology is usually difficult to achieve economic and clean and efficient utilization.
In order to achieve the in-depth advancement of the "dual carbon" strategy and guide the mineral processing technology to develop in the direction of high efficiency, energy saving, green and low carbon, low-carbon mineral processing technology at home and abroad has mainly carried out theoretical innovation and technical development in the direction of low-energy consumption crushing and grinding technology, high-efficiency separation technology, green and low-carbon agent development technology, short-process mineral processing technology and intelligent mineral processing technology, which has improved the efficiency of resource utilization, reduced energy consumption and carbon emissions in the process of resource development and utilization, and promoted the green development of the industry into a new stage.
The production of mining chemicals industry is highly refined, and its core competitiveness is mainly reflected in the selection of process routes, the development of product formulas, and the targeted optimization of flotation equipment. From the perspective of process route selection, manufacturers need to master process technologies such as reaction mechanism research and chemical synthesis process design in order to achieve product performance while controlling production costs and pollution emissions; from the perspective of product formula development, manufacturers need to develop various formulas through multiple experiments and form their own formula technology database to meet customers' diverse and personalized product needs; from the perspective of targeted optimization of flotation equipment, downstream customers' flotation process equipment has a high degree of integration, strict requirements on parameter accuracy, and it is not suitable to frequently start and stop equipment production lines. Only when the reagents and equipment processes are properly adapted can production efficiency and product quality reach the best level.
Competitors in the industry cannot complete technology accumulation in a short period of time, and therefore cannot produce high-quality, good-performance products that meet customer requirements. This is the key for existing companies in the industry to maintain their competitive advantage. At the same time, the industry's technology updates and iterations are relatively fast. The development of new products and the expansion of new application scenarios require companies to have a high level of technology and innovation capabilities, which makes the industry also have high barriers to technological innovation.
In the mineral processing reagent industry, the main customer group is the mineral processing plants under large steel groups. These customers have a strict supply chain management system and have high requirements for the performance and quality of raw materials. To become their supplier, you need to meet a series of strict conditions and follow a lengthy process. Before confirming the purchase intention, customers will conduct a strict pre-examination of suppliers, including analyzing and verifying the supplier's quality assurance system, after-sales service level, long-term stable supply capacity, the ability to assist in improving the level of application technology, and their own development potential, so as to comprehensively evaluate the supplier. In addition, before selecting a supplier, customers usually need to conduct a series of links such as preliminary sample analysis, small tests, evaluation, pilot tests, and re-evaluation. This process is lengthy, time-consuming, and expensive. Therefore, unless the original supplier has major quality problems or the production capacity cannot meet the demand, downstream customers usually do not easily change suppliers. Market barriers have become a difficult threshold for competitors to enter this industry.
The mineral processing agent industry has high technical requirements and requires high customized development capabilities. It spans multiple disciplines and industries such as chemical engineering, mineral processing, and environmental protection, and has high requirements for R&D talents with complex backgrounds. Industry enterprises have refined requirements in production processes such as chemical synthesis and formula research and development, and also have a large demand for production talents with fine chemical production experience and control capabilities. At the same time, talents with certain professional knowledge and experience are also needed in the aspects of safe production and quality control of mineral processing processes. The above talents in the industry are relatively scarce, thus forming a certain talent barrier.
The mineral processing agent industry belongs to the chemical industry, which has relatively high requirements for environmental protection and is supervised by the environmental protection department. The "environmental impact assessment and acceptance" policy is implemented during the investment and construction of projects. During the project design process, it is necessary to make reasonable arrangements for the treatment of "three wastes" in advance, and make corresponding investments in environmental protection facilities in accordance with relevant national regulations to ensure that environmental protection facilities are designed, constructed, and put into production at the same time as the main project. When enterprises start formal production, they must obtain pollution discharge permits in accordance with the law, the discharge of major pollutants must meet the national or local emission standards, and industrial solid waste and hazardous waste must be safely disposed of. Based on the trend of increasing domestic environmental protection requirements, the advantages of enterprises in environmental protection are an important part of the core competitiveness in the industry, and new entrants will face higher environmental protection barriers.
