Method for rapidly measuring weight of flotation foam product

Abstract

The invention provides a method for quickly measuring the weight of a flotation foam product. The method comprises the following steps: 0, presetting the minimum value Gs and the maximum value Gb of the weight of a foam product according to a test scheme, dividing Gb-Gs into n weight ranges at equal intervals, measuring the density delta i (i = 1, 2... n) of the weight of the n ranges, and calculating the average density delta; 1, during flotation, scraping the foam product into a sample receiver with volume scales; 2, weighing the weight M1 of the sample receiver in advance; 3, after flotation is finished, reading the volume V of ore pulp out from the sample receiver, weighing the weight M2 of the sample receiver containing the ore pulp, and calculating the weight M of the ore pulp; 4, calculating the solid weight m in the foam product; 5, according to the range of the m value, recalculating the weight mi of the solid in the foam product through the corresponding delta i value. In addition, in the same ore, delta i only needs to be measured once; if the absolute value of the delta i and the delta difference value is smaller than 3-5%, the step 5 is not needed. Compared with a conventional method, the method is rapid and efficient in measurement and does not change the ore pulp form.

Description

Technical field [0001] The present invention relates to the field of flotation test techniques, and more particularly to a method of rapid measurement of flotation foam product weight. Background technique [0002] The flotation test is to determine the pose of ore, determining that the ore flotation is suitable for important means to meet the flotation indicators, and provide a basis for the design construction and flotation production process adjustment for the selection plant. Flotation tests typically calculate product yields by weight of the product weight and unopened cells in the lower floating cell; the product test analysis is obtained; the recovery rate is calculated from yield and grade. It can be seen that the weight and grade of flotation products are two important raw data for calculating flotation test indicators. For yield, the foam product and the cell product are generally needed to separate, and the solid phase drying has been calculated after the yield. Becaus...

Problems solved by technology

The existing problems are: 1) When the foam product is the final product of the test, the method of solid-liquid separation-drying-weighing is slow, takes a long time, and cannot meet the immediate adjustment conditions. It is only used as an evaluation of the test effect Basis; 2) When the foam product is not the final product of the test, the judgment of the quantity can only be estimated generally, the error is 50%, or even exceeds 100%, and more than half of the tests are due to the inappropriate quantity, so the number of tests is increased, such as closed-circuit test, Often close the circuit 7-8 times, if the multi-metal separation, the number will be more

Not only does it cost more, it also wastes a lot of time and resources
