Includes bibliographical references. "Three suites of samples were obtained from the concentrator of Brunswick Mining and Smelting Corp. Ltd. over a two-year period to characterize the nature of the sphalerite, galena and chalcopyrite in the mill feed, in the zinc, lead and copper concentrates and in the plant tailings. The degree of liberation of each mineral and the size distribution of the free and unliberated mineral grains were determined using a Quantimet 720 image analyzer. These results were treated by the MATBAL 3 program to obtain a materials balance by appropriately adjusting the analyzed values. Generally, the required adjustments were negligible"--Abstract, page i. Includes abstract in French. gccst Minerals gccst Mining industry Petruk, W., 1930- author. Canada.
