The spot price for gold is in a constant state of flux, and can be driven by many different factors. The spot gold price can refer to the current price of gold per ouncegram or kilo. Typically, however, spot gold is quoted in price per ounce using U.Brown eyes quotes for instagram
Quotes are also available depicting the spot gold price in other currencies as well. Spot gold price charts can be useful for identifying trends in the gold market, or for looking for areas of support and resistance to buy or sell at. Charts can be viewed using multiple timeframes depending on your objectives. A long-term gold investor will likely be most concerned with weekly, monthly and yearly charts while a short-term hedger may be more concerned with daily, hourly or even 5 minute charts.
The simplest answer is the law of supply and demand. If buyers are trying to buy gold, sellers may lift prices causing buyers to bid higher. On the other hand, if sellers are overwhelming buyers, those looking to acquire gold may bid lower, thus driving prices down in the process. The actual spot price of gold is derived from the nearest month gold futures contract with the most volume. This could be the nearest month, or front month, or it could be a month or two out on the time horizon.
Gold is not only bought as an investment, but it is also bought for use in other areas such as industry and jewelry making. The potential influences on the spot price are extensive, but the following list names some of the major ones:.Supplier Discovery.

In increasing production from other countries and declining production from South Africa meant that China became the largest producer, although no country has approached the scale of South Africa's period of peak production during the late s and early s. In South Africa produced tonnes or 32 million ounces of gold, two-thirds of the world's production of Production figures are for primary mine production.
In the US, for example, for the yearsecondary sources new and old scrap exceeded primary production.

Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners. Hydraulic mining was used widely in the Californian gold rushand involved breaking down alluvial deposits with high-pressure jets of water. Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used.
Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low-grade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values.
The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation. The smelting of gold began sometime around - BC.
According to de Lecerda and Salomons mercury was first in use for extraction at about BC,  according to Meech and othersmercury was used in obtaining gold until the latter period of the first millennia. A technique known to Pliny the Elder was extraction by way of crushing, washing, and then applying heat, with the resultant material powdered. The solubility of gold in a water and cyanide solution was discovered in by Carl Wilhelm Scheelebut it was not until the late 19th century, that an industrial process was developed.
The expansion of gold mining in the Rand of South Africa began to slow down in the s, as the new deposits being found tended to be pyritic ore. The gold could not be extracted from this compound with any of the then available chemical processes or technologies. By suspending the crushed ore in a cyanide solution, a separation of up to 96 percent pure gold was achieved. The process was first used on a large scale at the Witwatersrand inleading to a boom of investment as larger gold mines were opened up.
The method known as heap leaching was first proposed in by the United States Bureau of Mines and was in use by the s. Gold occurs principally as a native metalusually alloyed to a greater or lesser extent with silver as electrumor sometimes with mercury as an amalgam.
Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial depositsor as grains or microscopic particles known as color embedded in rock minerals.
Ores in which gold occurs in chemical composition with other elements are comparatively rare. They include calaveritesylvanitenagyagitepetzite and krennerite. Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables.
Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold.
In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smelted to form gold bars. In other cases, particularly when the gold is present in the ore as fine particles or is not sufficiently liberated from the host rock, the concentrates are treated with cyanide salts, a process known as cyanidation leachingfollowed by recovery from the leach solution. Recovery from solution typically involves adsorption on activated carbon then stripping eluting the gold from the carbon and passing the pregnant solution through electrowinning and then onto the smelting process.
Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyritechalcopyrite or arsenopyriteand when such sulfides are present in large quantities in the ore.
In this case, concentration of the sulfides results in concentration of gold values. Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for final recovery of the gold.Jaw crusher as the primary crusher used in crushering all kinds of stone … PFW Impact crusher.
