The Centennial Quarry is a flooded quarry 2 miles north of the village of Silica in Sylvania Township. The rocks exposed are the Detroit River Group. This quarry was first described by Carman (1922) with having crystals of calcite in cavities and geology similar to the quarries south in the village of Silica.
Crystalline silica, a component of this product, has been designated by IARC as Group 1, a substance known to cause cancer in humans. Limestone is not listed as a carcinogen on the NTP, IARC, or OSHA lists of carcinogens.
The main aims of this study were to determine the chemical stratigraphy of the limestone units in the quarry so as to assess primary sources of silica in the intact limestone (host limestone); to use field methods to measure the nature and distribution of a variety of discontinuity features which separate the intact rock blocks within the ...

Mar 13, 2011· Freshly fractured silica dust appears to be more reactive and more hazardous than old or stale dust. This may be a consequence of a relatively higher surface charge on freshly formed particles. The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock.
Chemical Composition Of Stone Dust Prompt : Caesar is a famous mining equipment manufacturer well-known both at home and abroad, major in producing stone crushing equipment, mineral separation equipment, limestone grinding equipment, etc.
Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Non-occupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as non-industrial sources.

OSHA, after decades of scientific studies on respirable crystalline silica, adopted its first PEL in 1971; Silica exposure remains a serious threat to nearly 2 million U.S. workers, including more than 100,000 workers in high risk jobs such as abrasive blasting, foundry work, stone cutting, rock drilling, quarry .
It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way. It is the fine fraction of the dust, the respirable fraction, that is harmful to health when inhaled. Respirable crystalline silica is often abbreviated as RCS.
inhalation of silica bearing dust thus being at risk of developing silicosis, a fatal lung disease. Information on the chemical composition of the quarry dust is important as it forms a vital baseline for among others the detection of the undesirable health effects among the quarry workers. The aim of the study was

Silica is the name given to a group of minerals composed solely of silicon and oxygen, the two most abundant elements in the earth's crust. In spite of its simple chemical formula, SiO2, silica exists in many different shapes and crystalline structures. Found most
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
