Conventional earth-moving equipment, including scrapers and loaders, are used to mine the zeolite bed. Selective mining and blending during removal or stockpiling controls any variation in the purity of the ores. Sampling drill holes, the area being mined, the haulage truck, and the process stream are all used for quality control. Uses
