Treatment of Jinpeng mining machinery
as a pioneer of general contracting project in mining instry, Yantai Jinpeng Mining Machinery Co., Ltd. provides general contracting services for domestic and foreign customers, including beneficiation experiment, mine design, equipment manufacturing, installation and commissioning, personnel training and management contracting. Jinpeng people always adhere to the tenet of technology, high efficiency, quality, safety and customer satisfaction, Try our best to complete every project successfully<
according to the ore properties and ore feasibility study report, Jinpeng beneficiation engineer has developed a cyanidation process for the project, which meets the requirements of the project:
process description
1 feed screening system
the raw ore is transported to the raw ore bin by truck, the raw ore bin is equipped with a lattice screen, and the large particles on the screen are broken manually by hydraulic hammer, Until it falls into the ore bin, a belt feeder is installed at the lower discharge port of the ore bin, the materials are fed into the circular vibrating screen for screening by 1 ᦇ belt conveyor, the procts on the screen are fed into the waste separation device, the wastes are sorted manually and transported to 4 ᦇ belt conveyor by 3 ᦇ belt conveyor, and the procts under the screen are fed into the steel structure powder ore bin by 2 ᦇ belt conveyor
2 grinding classification system
the ore in the fine ore bin is fed to the 4 ﹥ belt conveyor by the belt conveyor, and then fed to the energy-saving ball mill by the belt conveyor. The discharge of the ball mill is pumped into the cyclone group by the slurry pump for classification, the underflow of the cyclone returns to the ball mill for regrinding, and the overflow enters the concentration leaching system after impurity removal by the impurity removal screen
3 thickening leaching system
the pulp is concentrated by the high-efficiency reformed thickener, the overflow flows into the circulating water tank, the bottom flows through the rubber pump into the leaching tank, and the leaching agent is added at the same time. After the two leaching tanks are pre leached, the activated carbon is adsorbed. The activated carbon is added to the final leaching tank, and then graally runs to the front leaching tank according to the regulations. When the activated carbon runs to the third leaching tank, the activated carbon is added to the final leaching tank, When the gold content meets the requirements, the air lifter is used to lift the vibrating screen for carbon slurry separation, the slurry is returned to the leaching tank, and the gold loaded carbon is sent to the desorption electrolysis system
4 Analytical electrolysis system
the gold loaded carbon enters the desorption column after washing and impurity removal in the carbon storage tank, and the desorbed solution prepared by the desorbing solution tank is fed from the bottom of the desorption column by heating and pressurizing, and the gold cyanogen complex in the gold loaded carbon is desorbed, filtered by the filter and then sent to the electrolytic tank for electrolysis to obtain gold mud
5 dosing system
there are many dosing points in the carbon pulp plant. In order to ensure the continuous and accurate dosing, Jinpeng's own patented touch screen computer dosing machine is used to control the dosing at each point, and the reagent mixing and lime mixing are matched
6 dewatering system
the final tailings of the leaching tank are pumped to the full-automatic box filter press through the buffer tank, and the filtered water flows into the circulating pool for recycling. The filter cake is transported to the tailings yard by belt conveyor, and the tailings are transported to the tailings pond by truck.
the following is the case of Jinpeng:
Sudan 1500t / D carbon pulp plant EPC project
Sudan Sahara 1000 / 500t / d
cil100t / D CIL plant (Indonesia)
1 million T / a tin ore dressing plant (Bolivia)
1 million T / a tungsten tin ore dressing plant (Kyrgyzstan)
adhering to the enterprise tenet of "pursuit of excellence, never-ending", the company constantly develops new procts on the basis of improving its existing procts. At present, the company has become one of the manufacturers with the most varieties and quantity of light steel keel in China. In terms of scaffolding ceiling keel, it is far ahead in China. The company exclusively proces national patent luxury stainless steel T-type light steel keel and V-type straight card ceiling light steel keel and other series procts. There are dozens of specifications and varieties. The company has strong technical strength, with a number of design patents., The brief introction is as follows:
main keel of ceiling, patent No.: ZL 01 2 18624.4
self connecting light steel keel, patent No.: ZL 97 2 31611.6 meinaiban, patent No.: ZL 02 1 53293.1
Pinoo was founded in April 2015. With its original social pinoo as the core mode, pinoo focuses on 10 billion subsidies, agricultural procts, good procts from different places, and is committed to serving China's most ordinary consumers
pinoo was born out of e-commerce of agricultural procts. According to the report released by renmin.com, pinoo has become the largest upward platform for agricultural procts in China. In July 2018, pinoo was officially listed on the US Nasdaq Stock Exchange
extended data:
through the decentralized traffic distribution mechanism, pinoo can greatly rece the traffic cost of traditional e-commerce, and make it beneficial to both sides of supply and demand. Based on the platform big data, pinoo helps factories to realize customized proction according to consumers' preferences and needs, continuously reces the cost of procurement, proction and logistics, and makes "low price and high quality" commodities the mainstream of the platform
pinoo platform has spawned nearly 1000 factory brands, and continuously promoted the supply side reform of multiple instrial clusters through c2m mode. In 2017, pinoo supported 180000 businesses in 19 instrial belts in the Yangtze River Delta, helped a large number of factories get rid of OEM status, and realized branding at the lowest cost
in December 2018, pinoo launched the "new brand plan" focusing on the growth of China's small, medium and micro manufacturing enterprises, aiming to support 1000 brand factories covering various instries, help them reach consumers effectively and cultivate brands at the lowest cost
