From August 26th to 28th, 2023 International Gold Industry Development Conference was officially held in Shandong. This conference focused on hot issues of gold and discussed ideas and countermeasures for innovative and high-quality development of the gold industry under the new situation. Xinhai Mining attended the scene with "Turn-key Service for Mineral Processing Plant (EPC+M+O)" and demonstrated Xinhai Mining's one-stop gold mine processing plant service model in detail, as well as its innovative technology and equipment for gold mines, attracted many customers to consult.

01Innovative gold ore beneficiaiton technology
Xinhai Research Institute adopts innovative thinking to formulate test plans for each ore sample, fully considering the characteristics of each ore. There are 29 innovative technological solutions in gold ore beneficiation alone.
01 Gold oxide primary mixed ore gravity separation + flash flotation process
Flash flotation is used to recover easy-to-float gold-bearing ore in advance, obtain qualified gold concentrate products, and reduce gold losses.
02 Flash flotation process for easy-recovery gold ore
◆Insist on timely flotation of high concentration and coarse particle size, early recovery of target minerals and increase the recovery rate of valuable minerals.
◆Reduce unnecessary grinding to reduce operating costs and increase the profit of the processing plant.
03 Innovative beneficiation process for easy-to-grind and hard-to-grind mixed gold ore
For difficult-to-separate ore, Xinhai Mining generally uses ultra-fine grinding + multi-stage separation to increase the recovery rate. Xinhai Mining adopts fine-grinding and flotation, the first-stage medium concentrate and the first-stage sweeping concentrate are combined to carry out the high-grade "medium ore regrinding and re-separation" process. In this way, it is not necessary to grind all the ore to -325 mesh, and most of the concentrate can be recovered at -200 mesh. Particles with finer embedded size are reground and re-separated in high-grade medium ore, which greatly reduces the cost and improves the comprehensive recovery rate.
02Gold ore processing equipment
The benefits of gold ore processing plants are closely related to the processing equipment. Xinhai Mining has passed the ISO9001:2015 international quality management system certification, EU CE certification and other certifications, and can produce and purchase gold ore processing equipment and equipment accessories in accordance with strict quality management standards. The combination of Xinhai Mining's innovative gold processing equipment and technology can greatly improve production efficiency, reduce energy consumption, and prolong the stable operation time of equipment.
03Xinhai gold processing plant cases
Xinhai Mining has gold ore EPC project cases in many regions around the world, and has rich experience in practical construction of gold mine projects. The whole chain, professional and institutionalized service system includes gold project design and research, gold equipment manufacturing and supply, equipment installation and commissioning, and gold project management and operation, provides powerful support for all links of "Turn-key Service for Mineral Processing Plant (EPC+M+O)" of Xinhai.
