Genetic dressing is imperative
Domestic and general process mineral processing (dressing) of the conventional technology research and development is Model: Process Mineralogy - Experimental Study dressing system (including small-scale tests, the test scale continuous, semi-industrial or industrial testing) - Recommended Flow Sheet - The Recommended Process and experience for the design of the concentrator - commissioning and commissioning.
Sun Chuanqi said: "The model has many drawbacks, such as long development cycle, high cost, low efficiency, and easy to waste due to repeated test work. Some of the day when the concentrator is put into production is the time of technical transformation. Individual concentrators even reach the service life. Still not up to standard."
For these drawbacks, Sun Chuanqi believes that there are three main reasons. First, the genetic characteristics of minerals, ores and deposits, which are the fundamental factors that restrict the beneficiation process, have not been systematically studied, tested and summarized. Second, a large number of existing mineral processing technology research data, process mineralogical data, production practice data, and previous design data and other large databases have not been established, and can not be effectively utilized. Third, modern information technology has not been reasonably deeply integrated with the research and development of mineral processing technology and engineering design.
“In fact, in the mineral processing science research, some researchers have consciously or unconsciously paid attention to and applied genetic characteristics, and have achieved certain results.†Sun Chuanqi said. But he also pointed out that the scattered research on minerals, ores and mineral genes is only preliminary and completely unstructured. So far, the process flow selected by the Trinity Gene Mineral Processing Engineering Research Method has not been seen, which is used for the practice of the mineral processing industry.
Break through traditional mineral processing
“It is very important to test whether the research method is scientific and efficient. Nowadays science and technology have developed into a new era, and it is possible to consider the use of genetic mineral processing engineering to re-innovate traditional research design methods.†Sun Chuanqi proposed genetic mineral processing engineering Say.
In order to promote the research on genetic mineral processing engineering, Sun Chuanqi proposed several research methods and technical routes.
1. Research and testing of genetic characteristics of minerals, ores and deposits
According to Sun Chuanqi, ore and mineral genes should be important factors in determining the selectivity, including the genesis and type of ore, the structure and structure of the ore, mineral composition, embedding characteristics, crystal size, dissociation characteristics, crystal chemistry of minerals, and Elemental composition, chemical bond characteristics, crystal structure type, surface and internal defects, and mineral surface characteristics. Using the various research methods of modern process mineralogy, systematically research and test the genetic characteristics of minerals and ores, propose a principle grinding process and selection process, and speculate on theoretical mineral processing indicators.
“The research and testing of the genetic properties of minerals, ores and deposits is the basis for the development of rational beneficiation techniques,†Sun Chuanqi said.
2. Establish and utilize large database technologies
"The vast ore process mineralogy research, genetic testing of mineral deposits, ores and minerals, mineral processing technology test, concentrating plant production practice data, and concentrating plant engineering design data, etc., historical, current, domestic, and foreign materials Collecting, researching, and establishing a database.†Sun Chuanqi said, “The establishment and application of database research is heavy and difficult, and it is the key to technology.â€
3. Deep integration of modern information technology and genetic mineral processing technology
According to the genetic research test results of minerals, ores and deposits, and through the established database, through intelligent selection, the ore selection process plan and the predetermined process indicators are initially proposed, and then the process and indicators are recommended through simulation of the virtual beneficiation plant. “Intelligent selection of process flow and simulation of virtual beneficiation plant are another key technology, innovative and difficult.†Sun Chuanqi said.
4. Limited ore dressing test verification
Conduct limited ore dressing test research on the recommended beneficiation process and indicators. The purpose is to verify the process and indicators recommended by the three-in-one of genetic testing research, big data technology and information technology. After successful verification, the application will be transferred to the application. Unsuccessful feedback to virtual simulation and database recycling was introduced.
5. Engineering transformation and data feedback
The confirmed beneficiation process and mineral processing indicators are officially used for the engineering design of the concentrator construction or technical transformation. The actual production data after production must be fed back to the virtual simulation and database.
“The research methods, technical routes and established information platforms of genetic mineral processing engineering may break through the traditional mineral processing R&D and engineering transformation mode, greatly shorten the development cycle of process technology, and achieve high efficiency and low consumption.†Sun Chuanqi concluded .
Strengthen the development of fine mineral processing technology
“Respecting and obeying the genetic characteristics of mineral resources and developing fine mineral processing technology that is in harmony with the selectivity of mineral resources is very important.†Sun Chuanqi said, “The development of mineral processing technology is no longer a rough sorting. In fact, many breakthroughs in process technology have been achieved through careful research on the target minerals and non-target minerals, and technical measures that may not be difficult.
Sun Chuanqi emphasized that we should strengthen the genetic research on the individualization of mineral resources, and use its natural and even slight differences in physical properties to expand the differences in sorting and achieve the purpose of high-efficiency separation of minerals.
Research on fine beneficiation technology includes research on ore and inspection of mineral processing products. The research on raw ore includes the type of ore, the chemical composition of the ore, the mineral composition, the content and state of valuable elements and associated elements, the structural structure of the ore, the embedding characteristics of minerals, the granularity and symbiotic relationship, and the valuable elements. Correlation calculation. For the sulfide ore, the phase of the crop should be determined to determine the oxidation rate. The iron ore is also determined in order to guide the pH of the subsequent sintering ore, pellet formulation. The copper ore also identify consisting of copper oxide, copper sulfide, and mineral content of the secondary primary copper sulfide, copper oxide ore to also identify the content of copper oxide is incorporated.
Sun Chuanqi believes that fine beneficiation technology should have several characteristics: reasonable grinding and grading process; respect mineral properties, and peaceful coexistence with minerals; according to the difference in mineral selectivity, the mineral particles can be divided and processed separately; early harvest (rough harvest) ), early loss (coarse throw), the middle mine, especially the Fulian body is handled properly; in the complex flotation process, the open circuit environment is properly formed, if necessary, the open product tail is produced, reducing the cyclic interference; the flow is simple Must be adapted to the efficient sorting of ore, not subjective.
