Sand mining - Wikipedia

Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads, usually mixed with salt, to lower the melting point temperature on the road surface.

Production of Silica Gel from Clay - sapub

The production of silica gel from the natural clay obtained from Kwali area council of Abuja was carried out using alkaline extraction followed by acid precipitation. The alkaline extraction was investigated using 4%, 15%, 25% and 30% (wt) sodium hydroxide solution at various reaction times of 1hr 1½ hr, 2hrs, 2½ hrs, 3hrs, 4hrs, 5hrs,7hrs and 8hrs.
