Iron (Fe) and water Water Treatment and Purification
Iron removal from water is mostly carried out in drinking water preparation, because mineral water contains high amounts of iron ions. These influence water colour, odour and turbidity. Iron is present in all wastewaters. Iron removal from wastewater may be achieved by oxidation of binary iron to tertiary iron.

Extraction Process of Aluminium from Bauxite Ore
Extraction Process of Aluminium from Bauxite Ore. The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue.
Environmental Impacts of Oil Extraction Sciencing
Oil is a commodity in high demand. While most people would not argue about oil's importance, whether or not we should access and extract oil from below the earth's surface is a subject of frequent debate. Drilling for oil, both on land and at sea, can have a number of effects on the environment.
