  • SAMPLING METHODS FOR IMPOUNDED TAILINGS

    The Ohio Copper Company 5 in 1928 sampled copper bear augers worked well in the dump slime, and the posthole augers worked well in the sands* Methods of Sampling Selected for Experimental Work The writer selected auger drills for the experimental work of sampling as past experience of others indicated that this method of sampling would yield the best results It was de­ cided that theThe aim of this paper is to inform about the sampling procedure of input materials of in secondary copper processing A representative sample is obtained by remelting The copper quantity in the(PDF) Methodology of sampling in secondary copper processingGrab sampling for underground gold J mine grade control known to contain less coarse gold than the highgrade shoots (30 g/t Au: ~60% of gold greater than 300 microns in size) In addition, stoping was via air leg methods which tend to yield a ‘finer’ rock fragment size range The Pajingo mine (Queensland, Australia) applies grab sampling to determine the grade of surface truck dumps prior toprocedures of sampling of gold dumps
