Mine beneficiation ball mills engineering design program to determine the selection of iron ore products to determine the significance of the program. This so-called solution is to study and determine the production of concentrate processing plant species (such as Guangdong, where the population has mixed ore concentrates and ore concentrates trial, the program concentrates two products), concentrate specifications, ore quality and other issues. It is designed to work in an important part, is to study and determine the sorting process, production measures and an important part of the level of equipment, but also a highly technical and economic work.
 Product solutions with the principles. Determine the product program should observe the following basic principles:
 Pay attention to market forecast. Products in the study program, should pay attention to concentrate production and marketing of the investigation, that is, concentrate consumption and price changes, concentrate production and marketing to ensure the right path. Sometimes, a metal can be recovered from the technology, but sell well, or the cost is too high, not immediately recovered, and in the design of certain amount of leeway. Comprehensive economic analysis. Concentrate in the development of quality standards, full account of user requirements. Do not think that the higher the quality the better concentrate, concentrate prices more than the more expensive the better, but to concentrate quality and recovery rates, sales profits, smelting and other production costs and complexity of relations, a comprehensive economic analysis, then determine the concentrate quality standards, so that the concentrator to obtain best value for money.
 Integrated to maximize the recovery of resources. Generally speaking, often accompanied by a variety of non-ferrous metal mining of valuable metals, such as recycling of metal, is to increase ore production and an important way to improve economic efficiency.
 Concentrate quality standards. By the Standardization Administration regulations, quality standards for non-ferrous metal ore concentrate into the national standard (GB), ministerial standards (YB) and the enterprise standard three (see the contents of the relevant standards). Premise in the above three criteria, the quality of supply and demand sides can negotiate the specific requirements of concentrate.
