24k Gold is a very soft and malleable metal in its pure form.  It can be made slightly harder by drawing the metal through a jewelers draw plate. 24k gold can also be rolled through a rolling mill.  24k gold is extremely soft when annealed for inlay jewelry work.  To join pieces of 24k gold, they should be fused.  We use 24k gold in Mark Ehrmann Jewelry Designs Keum-bu line of jewelry. 24k Gold is available in casting grain, sheet, round wire, coins-Ancient Byzantine gold coins and gold bullion coins, 1 oz disc, and bullion from 5-100 ozs.  The beauty of 24k gold is that one may also invest in gold bullion. 24K pure gold has a chemical symbol of Au, it melts at 1945 degrees Fahrenheit its specific gravity is 19.32 and its weight is 10.180 in Troy ounces.

We are offering Gold Bullion.A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. Three types may be distinguished: specie, exchange, and bullion. In the gold specie standard the monetary unit is associated with the value of circulating gold coins or the monetary unit has the value of a certain circulating gold coin, but other coins may be made of less valuable meta If the gold is still not pure enough, it can be smelted. Smelting involves heating the gold with a chemical substance called flux. The flux bonds with the contaminants and floats on top of the melted gold. The gold is then cooled and allowed to harden in molds, and the flux-contaminant mixture (slag) is hauled away as a solid waste.In the gold is still not pure enough, it can be smelted.

Throughout history, gold has often been the cause of both conflict and adventure: the destruction of both the Aztec and Inca civilizations, for instance, and the early Afica gold rushes to Ghana, South Africa, and Angola. Gold's one drawback for use in industry is that it is a relatively soft metal (sectile). To combat this weakness, gold is usually alloyed with another member of the metal family such as silver, copper, platinum, or nickel. Gold alloys are measured by karats (carats). A karat is a unit equal to 124 part of pure gold in an alloy. Thus, 24 karat (24K) gold is pure gold, while 18 karat gold is 18 parts pure gold to 6 parts other metal.

22k Gold has the 24k gold look but is made harder for jewelry and dental use by adding 8.3% alloy.  22k gold can easily be textured and formed into beautiful jewelry.  22k gold can be easily fused or soldered with 21k gold solder.  American Eagle gold coins are stamped by the United States Mint and are made with 22k gold. (1.000 oz gold, 0.091 oz alloy). 22K gold is also available in casting grain, sheet, round wire, sizing wire and bezel wire.  22k gold is also used in the process of granulation.

We are offering 14 carat gold. 18k gold is .752 fine, which is the european standard of 1824k gold and 624 alloy. 18k gold products are shanks for rings, stone settings, sheet, wires, bezels, grain, and tubing. there is also an 18k royal yellow gold that has more of an italian gold color which looks a little more green. about 65 percent of processed gold is used in the arts industry, mainly to make jewelry. Besides jewelry, gold is also used in the electrical, electronic, and ceramics industries. These industrial applications have grown in recent years and now occupy an estimated 25 percent of the gold market. The remaining percentage of mined gold is used to make a type of ruby colored glass called purple of cassius, which is applied to office building windows to reduce the heat in the summer, and to mirrors used in space and in electroscopes so that they reflect the infrared spectrum.

We are a reputed Supplier of 24K Yellow Gold Casting Grain from Cotonou. We have tie ups with the famous vendors and bring to you a collection that is 100% pure for sure. Our Yellow Gold Casting Grain is accurate in weight, strong and is highly durable for making jewellery. It is too soft and is accurately mixed with other metal alloys (silver, copper, nickel and zinc) to make it stronger. Rely on us! What is a karat? The karat indicates the amount of pure gold in the metal. Higher the karat, higher will be the percentage of pure gold in the metal. Is 10k harder than 14k or 18k? 24k gold is pure but too soft to use, so it is mixed with other metals to strengthen it 18k is 75% pure It is the European standard 14k is the most popular choice in the U.S

We supplied in kilogram and gram to the final destination of our numerous clients. Types of gold bar Gold bars are classified into two different types, cast and minted, based on their method of manufacturing.[1] Cast bars are made by pouring molten gold into an ingot mold to shape the gold product. Minted bars are made from gold blanks that have been hand cut to the required dimensions from a flat piece of gold. Markings are almost always applied by presses.

The gold is then separated from the ore using one of several methods. Floatation involves the separation of gold from its ore by using certain chemicals and air. The finely ground ore is dumped into a solution that contains a frothing agent (which causes the water to foam), a collecting agent (which bonds onto the gold, forming an oily film that sticks to air bubbles), and a mixture of organic chemicals (which keep the other contaminants from also bonding to the air bubbles). The solution is then aerated—air bubbles are blown in—and the gold attaches to the air bubbles. The bubbles float to the top, and the gold is skimmed off. Cyanidation also involves using chemicals to separate the gold from its contaminants. In this process, the ground ore is placed in a tank containing a weak solution of cyanide. Next, zinc is added to the tank, causing a chemical reaction in which the end result is the precipitation (separation) of the gold from its ore. The gold precipitate is then separated from the cyanide solution in a filter press. A similar method is amalgamation, which uses the same process with different chemicals. First, a solution carries the ground ore over plates covered with mercury. The mercury attracts the gold, forming an alloy called an amalgam. The amalgam is then heated, causing the mercury to boil off as a gas and leaving behind the gold. The mercury is collected, recycled and used again in the same process.

Gold, whose chemical symbol is Au, is malleable, ductile, and sectile, and its high thermal and electrical conductivity as well as its resistance to oxidation make its uses innumerable. Malleability is the ability of gold and other metals to be pressed or hammered into thin sheets, 10 times as thin as a sheet of paper. These sheets are sometimes evaporated onto glass for infrared reflectivity, molded as fillings for teeth, or used as a coating or plating for parts. Gold's ability to be drawn into thin wire (ductility) enables it to be deposited onto circuits such as transistors and to be used as an industrial solder and brazing alloy. For example, gold wire is often used for integrated circuit electrical connections, for orthodontic and prosthetic appliances, and in jet engine fabrication.

Placer deposits contain large pieces of gold ore (nuggets) and grains of gold that have been washed downstream from a lode deposit and that are usually mixed with sand or gravel. The three main methods used to mine placer deposits are hydraulic mining, dredging, and power shoveling. All methods of placer deposit mining use gravity as the basic sorting force. In the first method, a machine called a "hydraulic giant" uses a high pressure stream of water to knock the gold ore off of banks containing the ore. The gold ore is then washed down into sluices or troughs that have grooves to catch the gold. Dredging and power shoveling involve the same techniques but work with different size buckets or shovels. In dredging, buckets on a conveyor line scoop sand, gravel, and gold ore from the bottom of streams. In power shoveling, huge machines act like shovels and scoop up large quantities of gold-bearing sand and gravel from stream beds. Hydraulic mining and dredging are outlawed in many countries because they are environmentally destructive to both land and streams.
