Silica Sand

The copper and zinc smelter at Flin Flon uses the sand as a fluxing agent which, in the molten state, reacts with various impurities in the ore and produces a slag. The slag is drawn off with the impurities, leaving a more refined metal behind. Silica sand has a large number of other industrial uses depending on their characteristics. 1.
