N=C ( n production - α ) The above formula is a representative expression of the following formulas, so the following formulas can be written separately:    Yield N γ ≤ n - α for    Yield N ε ≤ n - α for    N β ≤ 2 (n yield - α as) In the middle   N - the number of original indicators required to calculate the process (excluding the number of raw ore indicators);       N γ - the number of yield indicators required to calculate the process;       N ε - each product is required when calculating the number of metal recovery process targets;       N β - the number of grade indicators of the metal in the product required for the calculation of the process;       n production - the total number of selected products required for the calculation process;       α 作—the number of sorting operations required to calculate the process;       C - The final product item of the calculation process or the number of items based on the weight of the material and one or more of the valuable ingredients in the material. Precautions 2. gold processing plant all kinds of original indicator selection The number of original indicators N required for the calculation process can be composed of different numbers of yields, recovery rates and grade indicators. However, only the product weight and grade indicators can be obtained in the process test. The yield and recovery are based on the product weight and For the calculation of the grade, the selection of the indicators is as follows: 1 ) In the process inspection, the original index selected is not the weight of the ore concentrate, but the weight of the intermediate product is generally not used as the original index. For the convenience of processing, the other products are all grade indicators. For the purpose of checking, the grade index of 1 to 2 intermediate products can be taken more than necessary and sufficient. 2 ) In the non-selection operation, the grades of the products are quite different (such as the grinding and grading operation of the gold concentrator), and it is necessary to indicate the grade change of each product in the operation. When the original index is selected, the grinding classification The work should be treated as a sorting operation and the product should be treated as a sorting product. 3 ) When there is re-election operation or amalgamation operation in the gold beneficiation process, a certain amount of cost is generated, and because of its small weight ( γ = 0 ), one grade index can be reduced. 800W hand -held immersion blender,electric hand blender ,hand blender turbo,Stepless Speed Hand Blender NINGBO CHENGTUO ELECTRIC APPLIANCE CO.,LTD , https://www.ctblenders.com
