The once primitive, cumbersome mining methods used during that time has developed into compact, efficient modern-day equipment that makes gold mining a more cost-effective, efficient process. Likewise, the mining equipment used today helps reduce waste and chemical exposure throughout the various phases of gold mining. The Basics of Gold Mining
Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms

Gold and silver ore mining companies typically retain ownership of the semi-processed gold or silver products and pay for further refining on a toll-charge basis. If you are an observer of the Gold and Silver Ore Mining industry, you will notice that the industry revenue is largely a function of production volume and commodity prices
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay
This method is now mainly carried out in Canada and South Africa. Off-shaft access. It is necessary to take into consideration the capability of the mine shaft to penetrate deep into underground mining. The process by which the horizontal working off the shaft is referred to as drifts, galleries or levels

Stamp mills were used by miners in Samarkand as early as 973. They were used in medieval Persia to crush mineral ores.By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. The basic design has not changed by much other than the drive mechanisms
Gold. In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Jaw crusher is a main type of rock crusher used to crush minerals or stones into smaller sizes. It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.
The compound crusher is used to crush a variety of medium hard ores, such as limestone, clinker,coal and other ores, which can be widely used in mining, metallurgy, refractory, cement, coal,glass, ceramics, electric power and other industries, and is one of the commonly used equipment in the crushing production line and the sand making production line.
