Processing (including preparation) makes food healthier, safer, tastier and more shelf-stable. While the benefits are numerous, processing can also be detrimental, affecting the nutritional quality of foods. Blanching, for example, results in leaching losses of vitamins and minerals. Also, milling and extrusion can cause the physical removal of

Tailings Dams. Tailigns dams are embankment dams constructed to contain and store waste (tailings) of mines. During mining, in order to separate the mineral or metal from the rock, mechanical and chemical processes are used to grind up rock into sand. The great amount of wastewater that is being mixed up with sand and chemicals is referred to
