Different types of gold ore

Different types of gold ore

"Types of gold ore" for gold is a relatively rare metal in the earth's crust, but a huge market for the metal and the need to extract. The study of different types of gold ores becomes a great deal of importance factors such as mineral conditions, economic growth and a trick of gold depends largely on the type that is extracted from ore. And gold ores can be classified under four broad heads: grinding raw materials, refractory ores, and PREG ores negative and complex ores.

Ores grinding

Milling gold ores are the most profitable. Quite logical, and ore types that fall under this category gold recoveries great promise, and sometimes even up to 99 percent. Best positive with this type ore is that it can be easily crushed, washed and crushed to recover gold contained therein. However, these are rare in nature. Quartz is the best example of this type of shooting during ore with a golden glow. Quartzrose


Refractory metals

Can ores that are refractory ores entails lower gold recovery, and that can be sometimes even up to 50 percent. But despite this, the sector is equally important and that for the simple reason that the free milling ores (more profitable) and very intimidating in nature to meet the growing demand for the metal. Cost of extracting these very high, due to the expensive processes such as oxidation, roasting and bacterial oxidation pressure required to obtain the pure metal. Methods such as cold or cyanidation are also popular to some extent result in a better gold recovery and thereby increase the overall profitability. And refractory gold ores consist primarily of gold deposits are not visible with a microscope. Gold sulfide also contribute to the major ore deposits heat. Copper and lead ores Coolers gold holder Coolers major holder of gold are the types of refractory ore.


PREG-robbed metals

Sometimes, as is the case the form of gold ran cyanide solutions in nature. The gold particles mainly to slip absorption fine-grained carbonaceous material present in the raw. These are referred to raw materials and ores PREG-robbed and these deposits are extracted gold with so much difficulty.

Ores complex

Complex ore extremely difficult (or even in some cases, impossible) to separate from its natural source. Sometimes extracted turns out to be useless to a large extent, and often is not taken in the first place. Gold and copper ores rich are characteristic of this group.
