Gold Material Introduction

Gold ore

Gold Ore

Gold is a dense, soft, shiny, malleable, and ductile metal. It is a chemical element with the symbol Au and atomic number 79. It has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits.

Gold ore mining processing plant

Gold ore processing plant is widely used in gold ore crushing and grinding process to resize and pulverize gold ores into 10mm to smaller than 1mm particles. As gold ore’s VHN hardness is between 60 and 105, SBM design gold ore crushing plant and grinding machine that can process gold ore. SBM gold ore processing plant includes mainly two series: crushing and grinding machines, both of which are welcomed by our customers. SBM gold ore crusher can produce gold products with the size between cm and mm. And our gold ore grinding machine can process gold ore into powder of nm grade.

Classification

State and gold content of gold in the mineral structure can be divided into the gold mineral gold deposits of gold minerals, gold-bearing minerals and gold - bearing minerals three categories. Independent minerals, means the so-called gold gold gold minerals and gold minerals in the form of output, it is the most important modes of occurrence of gold in nature, industrial development and utilization of the main object. So far, the world has found 98 gold minerals and gold-bearing minerals, common only 47 species, and direct industrial use mineral only 10 kinds of.

Distributed

The gold is distributed in South Africa,Ghana,Zimbabwe,Tanzania,Russia,Uzbekistan,Kazaksthan,Georgia,Kyrgyzstan,Tajikistan,China,India,Indonesia,Australia,USA,Canada,Mexico

Application

gold ore picture

1) is used as international reserves. This is determined by the monetary gold product attributes.History due to the excellent characteristics of gold, gold acts as a function of money.

2) is used as a decorative jewelry.

3) in the industrial and scientific and technological applications. Infrared reflectance close to 100% due to the gold have unique perfect nature, it has a high resistance to corrosion stability; good electrical conductivity and thermal conductivity; the gold nuclei having a larger neutron capture cross-section; ; also widely used in the most important modern high-tech industry, and electronic technology, communications technology, aerospace technology, chemical technology, medical technology.

Gold Processing

Most of the gold processing plant use jaw crusher as the primary crushing. CSB cone crusher is used as the intermediate crushing. The CSD cone crusher is as the fine crushing. The equipment potential to improve mineral production capacity, crushing process transformation, improve the utilization factor of the grinding machine, taken measures to implement the more crushing and less grinding to reduce the particle size of ore into the mill.

Flotation machine (also called Flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc. The impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp; on the other hand, to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board. When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remained slurry flows to the next trough until it becomes residue.

Gold Ore Processing Project Video

Video of Located approximately 57km south-west of Obuasi town and 195km north-west of Ghana's capital Accra

Located approximately 57km south-west of Obuasi town and 195km north-west of Ghana's capital Accra, the gold mining project is owned by Central Ashanti Gold Limited, a wholly owned subsidiary of Perseus, which owns 650km² of tenements on the Ashanti gold belt.

Gold mining is carried out to support a mill feed rate of 5.5Mtpa of high grade primary ore. Processing is carried out in a 5.5Mtpa gold processing plant that will include a primary jaw crushers, single stage SAG mill, gravity circuit, flotation circuit, regrind ball mill, concentrate CIL circuit and elution circuit. The whole gold mining project goes smoothly and with our products used, the whole plant’s efficiency can be adjusted smartly. We adhere to principle to provide quality products with excellent services for our Ghana customers.

Problems in the gold mining process

(A) comprehensive utilization of mineral resources, inadequate laws and regulations, the comprehensive utilization of mineral resources, preferential policies are not in place. Adopting both rich and poor, low-grade ore and to carry out the comprehensive use of recycling useful components associated with the taxes charged according to the amount and quality, increase the use of cost, profit margins are low due to the recovery of this part of the resources even needed capital subsidy, , engage in comprehensive utilization but affect the economic efficiency of enterprises.

(B) loss of mineral resources, waste and destruction Most of the gold mines, especially small-scale mining is often the case where the low level of exploration under construction. Mine put into production, infrastructure, technological transformation at the same time, the majority of small businesses in the metallurgical process technology, low management level, coupled with the initial mining program ill-considered, often resulting in a large loss of resources, waste and destruction.

(C) the development and utilization of tailings resource not enough, a variety of price associated elements have not been fully recycled, low environmental efficiency.

(D) investment in science and technology and personnel training is not enough emphasis Currently, the gold mine of comprehensive utilization of research are still weak, the depth and breadth of the comprehensive utilization of mineral resources research is not enough. On the one hand, the industrial sector dispersion of Geology and Mineral scientific research strength is not concentrated, apparatus, equipment, poorly equipped, do not form a fist. On the other hand, the comprehensive utilization of mineral resources, a serious shortage of basic research forces. Deployment of geological prospecting work, no deployment and comprehensive evaluation study on comprehensive utilization pilot study. Existing scientific research with low conversion rates.

Technology Standard

Machinery used in refining circuit

Once extracted, the gold ore is pulverized to prepare it for refining. The gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore.

In this refining circuit, we can use electrowining cells, electrorefining cells and remelt furnace to refine gold ore. we also can use filter presses, mercury retorts and induction refining furnace to purify gole.

Gold Ore Mining Procsss

In gole ore mining plant, we use equipments to purify glod from pyrite, chalcopyrite, native gold.

After gold ore mined, firstly go through crushing process. In the gold ore coarse crushing process, jaw crusher is used as gold ore primary crusher. After coarse crushing process, screen out the fine gold ore, the gild ore with diameter more than 10 mm go through secondary crushing process, in this crushing process, standard CS series cone crusher is used. In some large gold concentrator, there is fine crushing process after secondary crushing. In this fine crushing, short head CS series cone crusher is used as gold ore crushing machine.

After crushing process, the crushed gold ore enter into ball mill evenly through vibrating screen. Ball mill is essential gold ore beneficiation machine used to grind gold ore into powder less than 200 mesh. Gold ore powder go through classification and flotation to make pure gold.

According to the different requirements, we can disign gold ore mining process flow chart for the gold mine.
