Jul 11, 2010· Best Answer: Quartz and Silica Sand Silica sand is having a very high percentage of silicon dioxide; a source of silicon. Quartz sand is sand having a very high percentage of quartz. Because quartz is composed of silicon dioxide, silica sand and quartz sand are essentially the same type of sand. River and Mining Sand
The silica in the sand will normally be in the crystalline form of quartz. For industrial use, pure deposits of silica capable of yielding products of at least 95% SiO2 are required. Often much higher purity values are needed. Silica sand may be produced from sandstones, quartzite and loosely cemented or unconsolidated sand deposits.

Sand carried by the wind filters into nearby homes and clings to foliage, cars, machinery or whatever is in it's pathway. an open pit mine is a huge eyesore on the land. It is a dead area with only sand, lights, noise, and machinery. After a sand mining operation terminates mining an area they are required to reclaim the land.
In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment. Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.
Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica.
