Gold ore ball mill Gold ore beneficiation machinery Gravity ball mill

The gold ore grinding machine is the main equipment for grinding and grinding gold ore. Its job is to grind the crushed large-grained minerals until they are ground (reaching the required particle size for mineral processing) for mineral processing. Obtain high quality concentrate products.

Our company produces many types of gold ore grinding machines, including grid ball mills, overflow ball mills and long barrel ball mills. In addition to supplying ball mill equipment, our company also provides design and research, complete equipment manufacturing and procurement, debugging and Mining full industry chain services (EPC+M+O) integrating delivery, mine management and mine operation services. At present, our company has completed a number of machine projects for gold grinding mines (including full-industry service projects in the mining industry). Let’s take a look at some of the machine project cases for our company’s gold grinding mines.

1. Machinery project of Shandong Mojin Mine

The processing capacity of this gold mine project is 1000t/d. Its ore properties are low-sulfide ores with very low sulfur content. The types of metal minerals include: silver-gold ore, gold ore, sphalerite, galena, hematite, etc. Stone minerals are mainly quartz, sericite, feldspar, calcite, chlorite, zircon, apatite, etc. This project is a mining industry-wide service project undertaken by Xinhai. In the grinding part, the gold ore grinding machine configured by our company is an autogenous grinding machine. The designed process flow is: one section of open-circuit self-grinding and one section of closed-circuit grinding. Grading process (grinding fineness - 200 mesh accounts for 55%). During the grinding process, in order to increase the fine particle content, an appropriate amount of steel balls will be added to the barrel of the autogenous grinding machine to make it in a semi-autogenous grinding state. It is equipped with a hydrocyclone to form a grinding classification system. In the end, the gold concentrate grade of this gold mine project was 46g/t, and the gold recovery rate was as high as 92%.

2. Machinery project of gold grinding mine in Indonesia

The machine sub-project of this gold grinding mine is a mining industry chain service project undertaken by our company. Its processing capacity is 100t/d. According to the characteristics of the ore, the mineral processing process designed by our company is: washing-crushing-grinding and classification. -Cyanide leaching process. The grinding and grading part adopts a closed-circuit grinding and grading process. The crushed products are sent to the wet grid ball mill. After grinding, they are screened through a chip removal screen. The underflow flows to the concentrator for concentration. Finally, the The economic benefits of the gold mine project far exceeded expectations and were highly recognized by customers.

3. Tanzania gold grinding mine machine project

The machine sub-project of this gold grinding mine has a processing range of 150 tons per day. The main ore body in the mining area is quartz vein-type gold ore. In order to obtain high-grade gold, the customer sought our company's customized mineral processing services. Through test analysis, our company designed a two-stage closed-circuit crushing-two-stage closed-circuit grinding and classification-jigging and gravity separation-cyanidation gold extraction-analytical electrolysis-smelting gold extraction process flow for it. The grinding and grading part uses a two-stage closed-circuit grinding and grading system. The crushed minerals are sent to the wet overflow ball mill for grinding, and the cyclone equipment is used to complete the grinding and grading operation.

4. Sudan Gold Mine Machinery Project

The machine-based mineral processing project of this gold mine has a processing capacity of 300t/d. The mineral processing process designed by our company is: pre-screening - one-stage closed-circuit grinding and classification - concentration - cyanide leaching - desorption electrolysis - smelting - tailings Press filter dehydration process. In the grinding part, an overflow ball mill is used for one stage of grinding, and a cyclone group is used for classification in one stage. The sand settled in the cyclone is returned to the ball mill for regrinding until it is qualified.

5. Tanzania gold grinding mine machine project

In the machine sub-project of the gold grinding mine in Tanzania, the grinding process designed by our company is a two-stage fully closed-circuit grinding process. The equipment configured is a grid-type ball mill as the first stage of grinding and an overflow ball mill as the second stage of grinding.

6. Machinery project of Malaysian gold grinding mine

The machine sub-project of the 700t/d gold grinding mine in Malaysia is a mining full industry chain service project undertaken by our company. The grinding part adopts a two-stage closed-circuit grinding and classification process. After grinding by a grid-type ball mill, the product enters the chip removal screen for screening, and the screen underflow flows into the concentrator.

7. Zimbabwe gold mine ball mill project

In the machine project of Zimbabwe's 1000t/d gold grinding mine, our company provides a full mining industry chain service project. The gold grade in the raw ore can reach 6g/t. In order to obtain a higher gold grade, our company designed The process flow of crushing-grinding-gravity-cyanidation-desorption electrolysis-smelting-tailings dehydration is developed. The grinding part adopts a one-stage grinding-two-stage graded fully closed-circuit grinding process.

8. Sudan Gold Mine Ball Mill Project

A machine for grinding gold ore in the Sudan Gold Mine beneficiation project with a processing capacity of 500t/d. The gold content in the ore is 2.97g/t. Most of it is earthy minerals. The particle size of the minerals is -2mm, and a small number of particles can reach 70mm. Through mineral processing test analysis, our company designed a full mud cyanidation process for it. The grinding part adopts a closed-circuit grinding process, and the supporting design is: grid-type ball mill and hydrocyclone.

9. Tanzania gold mine ball mill project

The Tanzania gold mine project has a processing capacity of 1200t/d gold grinding machine. The ores are mainly sulfide ores and oxidized ores, and gold is the only valuable recoverable element. Our company has designed a full mud cyanide gold extraction process for it. The grinding part adopts a closed-circuit grinding and classification operation, in which a wet overflow ball mill is used for grinding and a hydrocyclone is used for classification.

The above are some of the mining industry-wide service projects our company has undertaken (more mineral processing project cases). According to the different mineral properties, our company has designed reasonable gold ore beneficiation processes for each mineral processing plant through mineral processing tests and analysis. process, and is equipped with reasonable mineral processing equipment and gold ore grinding machinery and equipment. In addition, our company also undertakes the packaging and shipping of equipment for each mineral processing plant, the installation, commissioning and operation of the project site, and the overall operation of the mineral processing plant.
