The installation and commissioning of the flotation column test line for Dingxin Copper Industry in Hami, Xinjiang have been successfully completed

Hami Dingxin Copper Industry Co., Ltd. (hereinafter referred to as the "Company") was registered and established on November 4, 2004 in Hami. The Company is located 210 degrees southwest of Hami City, 120 kilometers away from Hami City, adjacent to Provincial Highway 235. The company is currently funded by five shareholders including Xinjiang Jujin Investment Co., Ltd. and China Railway 19th Bureau Group Co., Ltd., with a registered capital of 600 million yuan. The company's business scope includes the mining of copper mines, processing and sales of copper products (limited to self-produced); Production and sales of electrolytic copper (limited to self-produced); Selling water.

On April 9, 2025, the Hami Dingxin Copper Industry Yandong Copper Mine project officially started construction. After completion, it will be combined with existing production capacity to form an annual output of 50000 tons of copper metal, becoming the largest copper metal production base in Xinjiang.

Hami Dingxin Copper Industry Co., Ltd. holds the mining rights of Hami Tuwu Copper Mine and Yandong Copper Mine. The copper metal reserves of Tuwu Copper Mine are about 932000 tons, with an annual processing capacity of 4 million tons of ore; The initial area of Yandong Copper Mine is 2.17 square kilometers, with an annual ore processing capacity of 5 million tons and copper metal reserves of approximately 1.64 million tons. The total copper metal reserves of Tuwu Yandong Copper Mine exceed 2.5 million tons, accounting for 3.1% of the current proven copper resources in the country.

To verify the application effect of flotation columns in copper molybdenum separation, Dingxin Copper Industry has built a flotation column experimental production line. After multiple rounds of technical exchanges with Jumu Mining, it was decided to conduct experimental research using the flotation column developed by Jumu Mining.

The inflatable experimental flotation column produced by Jupiter Mining is a testing device that generates bubbles through the instantaneous explosion of high-pressure gas, especially suitable for fine-grained minerals with high dissociation degree. This device has developed a dual-mode test to address the industry pain point of high ore volume in flotation column testing. In the cyclic mode, the amount of flotation column test samples can be significantly reduced, solving the problem of difficult flotation column condition testing.

This type of experimental flotation column has the characteristics of good selection indicators, simple operation, easy maintenance, high degree of automation, and is particularly suitable for experimental research. It can be independently or combined as a set, and the flotation process can quickly change with different ores. The new experimental flotation column has been successfully applied in some research institutes and universities in China, and has received good market response.
