Extracting Minerals from Seawater: An Energy Analysis

extraction in amounts comparable to the present production from land mines would be impossible because of the very large amount of energy needed. This conclusion holds also for uranium as fuel for the present generation of nuclear fission plants. Nevertheless, in a few cases, mainly lithium, extraction from seawater could provide amounts of metals sufficient for closing the cycle of metal use ...

Sand mining

Sand mining

Sand mining is the extraction of sand, mainly through an open pit (or sand 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 is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.

Silica

Silica

Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone. As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand. World consumption approximates 120 Mt/year. Quartzite, sand ...

Hydrocyclone Liners. Hydrocyclone desanders are used in subsea oil extraction for the process of separating sand from the oil. International Syalons manufacture silicon nitride based sialon ceramic hydrocyclones liners for these desanders. Hydrocyclone desanders work as a result of pressure differences in the slurry which generates centrifugal forces which causes rotational motion of the fluid.

Silicon, one of the most common elements on earth, is generally refined from sand, but it could also be sourced from glass. Silicon production is energyintensive, requiring a temperature of 1700 degrees Celsius. Now, in the online journal Angewandte Chemie, UW–Madison's Song Jin, with UW researchers Dong, Tyler Slade, and other colleagues, have published a recipe for a simpler ...
