In contrast to the production of commodity chemicals, batch manufacturing requires that the raw materials, processes, operating conditions, and equipment change on a regular basis to respond to the needs of customers. Despite the large number of chemicals available in the market, electrochemical synthesis of chemicals has been limited to a narrow
They are used in many largescale industrial processes. They produce chemicals such as ethanol, which is used as a fuel, solvent and for many other purposes, as well as glycerol, a common metabolite in food and medicine, and a number of other chemicals. Microbes are also used in a process called bioleaching, in which bacteria leach metals such as iron and manganese from soil and sewage.
Large quantities of salt are precipitated during this process, which is normally reused to produce a saturated brine feed to the cells. An additional aspect of the sodium hydroxide produced in the diaphragm cell is that the product has a small amount (1%) of salt present as a contaminant, which may make the material unsuitable for some purposes.
Many largescale mines also have ore processing facilities where extracted ore is sent for crushing, washing, and various physical or chemical separation processes. Not all mined materials are dangerous, but many heavy metals and naturally radioactive materials that are removed from the earth can be very hazardous to human health.
Distribution of gold is not found evenly across the country of China. Most of the countries production has taken place in the provinces of Shandong, Fujian, Henan, Hebei, and Liaoning. Most large scale mining operations in China are mining gold ores from hard rock deposits.
LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
