6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

What is white kaolin clay? 1 LB White kaolin clay is one of the gentlest face clays available. It contains kaolinite, which is a layered silicate mineral. While the mineral may be found all over the world, it has long been mined in China's Kao-ling Mountain. Kaolin clay is good for practically all skin types, particularly sensitive skin.
