Tin processing

They are mined by one of several surface-mining methods, principally gravel pumping, dredging, and, to a smaller extent, open-pit mining. A large proportion of tin ore is mined by gravel pumping. In this method, the barren overburden is removed, often by draglines or shovels, and high-pressure water jets are used to break up and dislodge the tin-bearing sand.

Properties of Graphene – Graphenea

Graphene Structure. Graphene is, basically, a single atomic layer of graphite; an abundant mineral which is an allotrope of carbon that is made up of very tightly bonded carbon atoms organised into a hexagonal lattice. What makes graphene so special is its sp2 hybridisation and very thin atomic thickness (of 0.345 nm). These properties are what enable graphene to break so many records in terms ...
