Do you know where it comes from gold?

Different ways to get the gold depending on the type of sediment are obtained two gold in two steps that are essential:First get rough .... Secondly separate gold oreAnd is the way the first exploration sediment or veins mineral underground and up prospectors for gold digging corridors header in the ground Mtaatbaan direction race and there are some gold ore is excavated on the surface of the ground breaking rocks put explosives inside and dig and then taken rocks containing gold to the mills, using giant hydraulic It helps to pump water and push strongly toward rubble gravel content on the gold Wegervh to vessels have thickly book Gold also sling a machine gold mining powered and consist of a number of buckets mounted on a compound every bucket capacity of 0.2 m 3 and down buckets of water on the arm sling and spin circular motion 0 Calcaekaya) to lift the silt from the bottom of the river and carrying sling devices separating the gold from other substances also Elmejrav robot which machine a huge gathering large amounts of soil, silt and gravel containing gold from river beds and works Elmejrav with other devices to separate the gold from other materialsFrom here we move on to another stage, a stage of separating the gold from ores or sea water and used three ways:1 - Buoyancy: excreted in the process buoyancy particles raw ground soft from each other based on the ability of various minerals found in raw linking itself with foam oily mix oils and chemicals called factors buoyancy water before mixing raw powder and used three types of chemicals which factor foamy and factor Collector and chemicals inorganic NES Vispb factor foam in puffing water and be Group of the Whole layer on the gold make it stick Bubbles air that float on the surface either chemicals inorganic turn off the spigot other minerals from the composition of the class which was dressed with gold shall be deemed a raw water enters the air in the solution and called This process ventilation and thus carrying gold particles to the top and Takect foam layer.2 - cyanide method: a process containing a raw powder in a tank containing a dilute solution of cyanide and then separates the gold in solution or deposited with zinc metal3 - pulp carbon: which is another way you need to use cyanide and where are first mixing raw powder with water to get to the door and then melted content of gold in solution of cyanide and added carbon particles to door to collect gold ions on the surface and then still carbon particles from pulp then placed particles in solution alkaline cyanide a hot caustic substance which in turn separates the gold from the carbonAnd يسبك gold with other metals such as copper and silver to make many kinds of jewelry white gold is made of gold cast with other metals such as platinum or palladium or silver often used as a framework for precious stones in rings and hoops and making gold chips melted metal is in the form of a rod then passes between Vaftin that becomes a strip flat clean fish on 0.04 m and then cut the ribbon to square pieces offer 2.5 cm and placed the pieces between slices of paper delicate cardboard, called pile containing 210 of gold chips cut and wrapped them in parchment, a parchment-like Balrkoq and placed on the cutting marble and touched a hammer weighs about 8 kg and this way prevents chips or panels into squares display 9 cm and every one of them cut to four squares and placed between parts made of plastic coated specially traditionally placed panels between leaves of the membrane called skin wrought gold made of gut bull Turning panels then hammer weighs 4.5 kg for twenty minutes and then cut each panel again to cut and touched pieces with a hammer weighing 3 kg this process transformation after four hours to shingles thin to the point that light shine through as thick around .00013 mm and then pick up the chips with pliers, wooden and placed on the cushions skin and trimmed with a knife or blade made of plant Alratan chips square width 9 cm 2 and 25 pieces of chips theme paper between pages and be a bookAnd can determine the caliber of gold through a knowledge of the hallmarks which sealed so as to show the purity of gold and clarify carat gold as well as the place where the analysis
