AbstractAt the request of the mining industry the ore dressing laboratories of the Mines Branch undertook to establish master sieves for standardization of sieves of the mining industry. The purpose of this work was to establish a standardized screening technique, thus placing all the operators of grinding plants on one basis of sizing. Three sieves of each of the following Tyler meshes were purchased: 48, 65, 100, 150, 200, 270 and 325. The Lake Shore method of standardizing the above testing sieves was used. After a series of self-checking tests with each sieve was made, the three sieves of each mesh were marked in the order of their decreasing fineness as master screen No. 1, No. 2 and No. 3. Three different ores were used for standardization of the 48, 65 and 100 mesh sieves, and four different ores for the 150, 200, 270 and 325 mesh screens. In the concluding paragraphs of the report, the results are summarized, conclusions are drawn, and suggestions are made to mill operators who wish ta have their screens standardized.
