Did You Know About Gold Mine.

Gold mines in Indonesia and How The waste processing.
Indonesia has a wide range of minerals contained in the various regions. Petroleum, natural gas, gold, coal, iron ore, and asphalt are the types of materials owned by the Indonesian mines. One type of material that is pretty much mine and spread availability in Indonesia is gold. Gold is one type of mineral that has a very high economic value. Gold is almost marketed and traded in almost all mineral trading markets around the world. The investment value of gold increases every trade gold occurs in large enough quantities. In fact, if seen further, gold in the form of foreign exchange contributed greatly to the gold exporting countries.
Gold is not in the ground deep enough layer of the earth's surface or the surface of the soil. It could be said that this type of mining is located on the surface of the soil, watersheds containing mineral deposits, even in an area downstream end of the river water flow direction may be a gathering place for the direction of the flow of several rivers that carry sediments minerals. Gold is a mineral that has many benefits. This mineral can be used as an introduction conductor of heat in some kind of electronic device. However, the main utility of gold is as a form of necklace jewelry, gold, rings, and so forth. So, in outline, gold has many benefits to human life.
To get the gold which is located at ground level or are located in the watershed is not too difficult. His search using only simple tools. Search techniques and the processing of waste is very simple. However, to get the gold in soil layers with a certain depth, prospecting should be used technological tools and search techniques are quite difficult. Survey location is one of the initial activities needed to determine the amount of available gold, gold position or location, and depth of gold from the ground. Areas that have a lot of availability of gold of course should be the basis or source of waste processing search results and gold exploration. Regions is then a gold mining areas which may be nature and the environment can be damaged due to the gold mining activities.
The gold processing in addition to advantageous also can give some negative effects. In addition to excessive nature exploration, gold mining and processing of gold will produce waste that can pollute the environment. The case of waste pollution due to gold mining occurred in the waters of one Buyat Beach. Allegations of heavy metal pollution in coastal waters Buyat as solid waste disposal (tailings) should not be the case, if the waste before disposal processing performed first. Waste treatment aims to reduce the levels to a minimum if possible even totally eliminate toxic substances contained in the waste before the waste is disposed. Although the rules and procedures for the disposal of toxic waste have been set by the Government in this case the Ministry of Environment, but in practice the field, there are still many pollution due to industrial waste. Perhaps the lack of supervisory personnel in addition to the sewage treatment process usually requires a considerable cost. Heavy metal is a metal that is large relative atomic mass, group these metals have a very important role in industrial example: Cadmium Cd batery used for materials that can be recharged. Chromium Cr for brilliant color giver or verkrom in tooling of metal. Cobalt Co to strong magnetic material on the loudspeaker or microphone. Cu for copper electrical wire. Ni nickel for stainless steel or stainless steel. Lead Pb for materials or Accu battery on the car. Zinc Zn coatings for cans. Mercury Hg dissolves the gold so much used to separate gold from a mixture with the ground, and the thermometer fillers and many more uses heavy metals that I may not mention all of them here. Just a pity so many potential uses in addition, heavy metals group is highly toxic eg Hg, Cd and Pb Cr and others. Plus accumulative nature in the human body, which after these heavy metals into the human body, usually through contaminated food heavy metals. These heavy metals can not be removed again by the body so that the longer the amount will increase. If the new numbers have been fairly large negative effect on health is beginning to look, usually these heavy metals accumulate in the brain, nerve, heart, liver, kidneys that can cause damage to the tissues they occupy. The spread of heavy metals in the soil, or air peraian through various things, for example, direct disposal of industrial wastes, either solid or liquid wastes, but can also be through the air as much as any industry that burns waste and dispose of combustion products into the air without any treatment first. Many people assume that by burning the toxic waste will be lost, when in fact we are just moving and spreading the toxic waste into the air. Pollution in this way is more dangerous because the air is more dynamic so that the resulting impact will also be more extensive and far more difficult to clean the air.
Waste processing technology with Phytoremediasi system, using plants as a means of processing contaminants. In solid or liquid waste to be processed, planted with certain crops can absorb, accumulate, degrade certain pollutants contained in the waste. Many terms are given in the system in accordance with the mechanisms involved in the process. For example: Phytostabilization, ie pollutants in the soil stabilized by the influence of the plant, Phytostimulation: destruction of pollutants stimulate plant roots with the aid of rhizosphere bacteria, Phytodegradation, which degrade plant pollutants with or without saving it on the leaves, stems or roots for a while, Phytoextraction, namely pollutants accumulate in the tissues of plants, especially leaves, Phytovolatilization, ie pollutants by plants is converted into volatile compounds that can be released into the air, and Rhizofiltration, the pollutants are taken out of the water by the roots of plants in hydroponic systems.
The process of remediation of pollutants from soil or water occurs because certain plants can release substances that carriers usually a chelating compounds, proteins, glucosides that serve specific binding pollutants are then collected in the plant tissue, for example on the leaves or roots. The advantages of such phytoremediasi system is low cost and can be done there, but the drawback is that it takes such a long and fertilizer required to maintain the fertility of crops, root crops are usually short so it can not reach the deep soil. The thing to remember is that once harvested, the plants are likely to still contain toxic pollutants must be addressed. So, thank you for reading this article.
