The processing of granite dimension stones essentially involves the following major operations: quarry opening; blasting; cutting; polishing and ornamenting. Quarrying for dimension stone requires a specialized method of extraction. Normal quarrying methods use large quantities of explosives to move huge volumes for breaking down into aggregate.
rectangular are for dimension stone production. In the mine, some of the cut dimension stone are 1m², while many are rectangular in shape. The size of the rail shape design for the primary stone production is 1m at the mine as shown Figures 3, 4 and 5. Fig4.

This paper presents the results of a new method that has been tested to recover metallic cobalt lost by diamond beads from rock cuttings. When dimension stones are cut using diamond wire saws, the beads become worn and, before the end of their cycle life, lose a certain amount of material; this material is prevalently made up of sintered metal and diamonds. The …

Dimension stone is quarried by cutting, or separating by some other means, large blocks of stone from the natural rock mass. The size of individual block produced depends on a number of factors, including the homogeneity of the rock itself, the ability of the quarry operator to handle the rough stone, and the required end use for the stone once it has been shaped.
