The sampling and estimation of the metal present in an ore dump or a tailings heap are matters which are of considerable importance to most men connected with the mining industry as they are often called upon to handle this class of work either tor themselves or for others

Although it is difficult to come up with an average composition of tailings since the composition will vary with the source and nature of the ores being mined at any given time the following general figures may be utilized Montreal Engineering Company 1975 Wilson 1976 Mineralogical composition of copper cliff tailings Sample size not

The concentrate and tailings produced average 327 and 018 copper respectively I let you do the math Three product bimetallic formulas Frequently a concentrator will mill a complex ore requiring the production of two separate concentrates each of which is enriched in a different metal or valuable mineral plus a final tailing

Minor metals expressed in mgkg are mainly represented by copper and manganese The tailing has a copper concentration above 1500 mgkg which is considered high for residual waste because the tailing used came from an old deposit and was produced by less efficient processes of ore flotation

MLA to evaluate differences in the mineralogical composition of the ore minerals Results and Discussion A total of 81 tailings samples were analyzed using XRF during the survey sampling The copper grade of the tailings varied between 01 and 17 Further elements of interest were iron gold molybdenum and zinc

Some ores such as iron ore are found in relatively high percentages and are fairly easy to separate Therefore the resultant tailings are coarser than those from other ores such as copper which is found in very low percentages and requires very fine grinding for separation Hence copper tailings are usually quite finegrained
