For the processing plant, the various beneficiation process indicators are directly related to the level of effectiveness of selected plants, is essential. So for some of the major indicators of beneficiation process is necessary to know in order to be able to play a guiding role in the actual production of selected plants. As we briefly explain learned from Xinhai mining machine data
Beneficiation process criteria are: grade (ore grade, concentrate grade), yield, beneficiation ratio, high-grade ore ratio, metal recovery.
One grade
Taste is actually a product of the metal taste, is the product of the weight of the metal weight ratio for the product. Grade general chemical analysis (or other methods) to determine, as a percentage. For example: copper concentrate grade of 20%, that is, containing twenty tons of copper in concentrate in dry tons.
Usually represented by the Greek letter grade, specifically: α-- said ore grade, β-- said concentrate grade, δ-- said tailings grade.
Taste for dressing plant, it usually want to improve ore, concentrate grade, reduce tailings grade. The main reason is because the metal content of ore grade level representative number, concentrator processing high-grade ore and low-grade ore effect is not the same. Processing high-grade ore, we must concentrate the amount obtained under the same conditions than the processing of low-grade ore. At the same time they can reduce costs and grinding balls consumption. So, ore grade is a factor affecting the level of concentrate production. At present, some concentrator began to gradually take some measures to improve the ore grade, such as installing Dry magnetic pulley in the broken system.
With respect to the ore grade, and strive to improve concentrate grade of greater significance. Concentrate grade improvement can increase concentrate prices, to enable enterprises to increase profits. It is important from a global perspective, energy-saving effect is very large. In iron ore, for example, concentrate grade increased by 1%, the blast furnace pig iron production rose 2.5%, coke rate fell 1.5%, the effect is very obvious. Similarly non-ferrous metal ore grade increase, regardless of the smelting operations have greatly benefited from the production or consumption. Therefore, to improve the concentrate grade, is one of a very important indicator mineral processing.
For the tailings grade level, can be seen in three aspects: 1, how the enterprise management level; 2, the process is reasonable; 3, change the nature of the ore. Therefore, efforts to reduce tailings grade, reduce metal loss, there is a certain relationship with the increase in production, especially in the more important for non-ferrous and rare metals.
Second, the yield
Product weight to weight ratio of ore called the yield of the product, including fine mineral ratio and tail minerals rate. Yield by the Greek letter Υ (read gamma) on behalf of the unit as a percentage. For example: a processing plant processing 500 tons of ore a day and night, to get 30 tons concentrate, then fine mineral was: Υ = (concentrate weight / concentrates weight) × 100% = (30/50) × 100% = 6%. Last Minerals rate: Υ tailings = [(ore weight - concentrate weight) / ore weight] 100% = [(500-30) / 500] × 100% = 94%, or with this calculation: Υ tailings = 100% -Υ concentrate.
Third, beneficiation ratio
The weight ratio of the weight of the ore concentrate on is called beneficiation ratio. This ratio can be derived by calculating get a ton of raw ore concentrate tonnage required.
Fourth, the high-grade ore than
Concentrate ratio percentage and ore content of useful components useful in the percentage of ingredients called Bonanza ratio (or enrichment ratio).
Five, metal recovery
The purpose of processing operations is to opt-in metal ore concentrates, the full extent of the selected sub-processes of ore in the weight ratio of the metal used to assess the weight of the metal concentrate, this ratio is called the metal recovery. Usually represents the Greek letterε expressed as a percentage.
Metal recovery plant is crucial for the election, which means ore dressing plant selected from a number of other metals, directly linked to the interests of the selected plants.
