About Emery Stone

Emery stone, also known as corundite, is a dark, granular rock primarily composed of corundum (aluminum oxide) along with other minerals such as spinels and rutile. It is widely used to create abrasive materials for grinding and polishing due to its hardness. The use of emery dates back over 2,000 years, with references found in Pliny the Elder's writings. The Greek Island of Naxos was historically a significant supplier of emery. However, its demand has diminished in recent years due to the advent of synthetic abrasives. In 2024, major suppliers of emery include Turkey and Greece, with applications expanding into cosmetics for nail care and skincare products.

Properties of Emery Stone

Emery stone, primarily composed of corundum (Al₂O₃), exhibits notable properties. Physical properties include a Mohs hardness of approximately 8 to 9, making it highly abrasive and suitable for polishing and grinding applications. Its density ranges from 3.5 to 4.0 g/cm³, contributing to its use as a nonskid material. Chemical properties involve the presence of iron oxides, such as magnetite (Fe₃O₄) at about 5-20% and hematite (Fe₂O₃) at around 1-10%, which can affect its colour and performance. Additionally, emery may contain other minerals like diaspore (AlO(OH)) and gibbsite (Al(OH)₃), influencing its overall composition and utility in industrial applications.

Manufacturing Process of Emery Stone

The production process of emery stone begins with mining and extraction, where deposits are identified and mined. Once mined, the ore undergoes crushing, breaking it down into smaller pieces to facilitate further processing. The crushed material is then subjected to grinding, where it is processed to achieve a specific grain size that corresponds to the corundum crystals. Following grinding, magnetic separation is employed to remove iron oxides and other impurities. This is often followed by chemical treatment, where the material is treated with hot acid to dissolve softer components, further purifying the corundum. After chemical treatment, the material is thoroughly washed and filtered. Next, the purified emery stone is dried to prepare it for final processing. Once dried, the material undergoes classification, where it is sorted based on grain size and quality. Finally, the finished emery stone is packaged for distribution.
