Engineered stone is also known as composite stone, manufactured stone, artificial stone, reconstituted stone or quartz conglomerate. The crystalline silica content in engineered stone varies widely but it can contain greater than 90 per cent crystalline silica
· The quartz stones are made up of several different minerals, but silica is one of the most common. This mineral makes the quartz stone so durable and can be used for so many purposes. People can find this material in just about any environment they choose, but most of it comes from the United States, Canada, or Russia.
· Engineered quartz presents possibly a greater danger of causing silicosis among people who breath in the dust from it as they cut and process it than sandstone, granite or slate. In a report this week in the American Morbidity and Mortality Weekly Report, researchers from California, Colorado, Texas and Washington identify 18 cases of severe silicosis, including two …
Special Silica Stone Uses "Silica stone" is an industrial term for materials such as quartzite, novaculite, and other microcrystalline quartz rocks. These are used to produce abrasive tools, deburring media, grinding stones, hones, oilstones, stone files, tube-mill liners, and whetstones.

Because quartz, a type of crystalline silica, is commonly found in stone, workers who cut, polish, or grind stone materials can be exposed to silica dust. Recently, silicosis outbreaks have been reported in several countries among workers who cut and finish stone slabs for countertops, a process known as stone fabrication (2-5).

· Quartz ore crushing. A jaw crusher is selected for crushing quartz stone to a particle size of about 150 mm. The advantages of the jaw crusher are large throughput and feeding size, simple and convenient maintenance, and low cost. Quartz stone is a material with higher hardness, so the cone crusher is the best choice in the second-stage crushing.
These other substances and quartz are polymorphs of silicon dioxide and belong to an informal group called the Quartz Group or Silica Group. All members of this group, except quartz, are uncommon to extemely rare on the surface of the earth and are stable only under high temperatures and high pressures or both.
· Quartz fiber is an ultra-pure silica glass that is typically processed into thin amorphous filaments of just a few micrometers (μm) in diameter. Using a choice of proprietary processes, these filaments can be collected either in the form of continuous strands – which are later processing into yarns of rovings – or as a form of felt and wool.
· Quartz and Silica Minerals Gallery. Andrew Alden is a geologist based in Oakland, California. He works as a research guide for the U.S. Geological Survey. Quartz (crystalline silica or SiO2) is the most common single mineral of the continental crust. It is unusually hard for a white/clear mineral, hardness 7 on the Mohs scale.

· Silica, or silicon dioxide, can exist in three main crystalline forms in nature: quartz, tridymite and cristobalite. These crystalline forms are contained in many natural materials, such as granites, porphyries, quartzites and sandstones, but also in various ''industrial'' materials, such as engineered stones and ceramics.
