Xinhai Mining is making steady progress in the 1.2 million tpa copper ore dressing plant project in the Middle East. The design of the ore dressing plant in this project follows advanced and reliable process technology, and uses large-scale and efficient equipment and advanced control technology, aiming to create an efficient and economical production system with optimized input. According to the contract with the customer, Xinhai is responsible for completing the construction drawing design, including the general plan, ore dressing process, electricity, water supply and drainage, tailings and other professional designs, and formulates efficient and reliable process flow through ore selectivity tests.

Xinhai Mining successfully completed the flotation expansion project of the 1500TPD silver-lead-zinc-gold polymetallic mine in Henan Province, China. It provides a full range of services for the technical transformation and expansion of the mine. The project includes the construction and renovation of multiple core facilities such as the intelligent waste disposal system, powder ore bin, grinding workshop and flotation workshop, 18m thickener, concentrate filtration workshop renovation, high and low voltage substations and 2000m³ high-level water tank. During the construction process, facing the complex construction conditions such as small site, demolition and construction, and frequent rainfall during the flood season, Xinhai relied on its professional first-level qualification for general contracting of mining engineering and rich project management experience, and was not afraid of challenges, ensuring the project was delivered on time with high quality.

Xinhai Mining successfully promoted the construction of Xinjiang 50,000 tpd low-grade ilmenite beneficiation plant project. The project mine area is rich in resources. After multiple surveys and detailed investigations, the preliminary exploration of iron ore resources has reached 251.1065 million tons and TiO２ metal content has reached 14.0659 million tons, providing sufficient guarantee for future mine development.

Xinhai Mining successfully delivered and promoted the Shandong 100,000 tpa Ultrapure Iron Concentrate Project. The project relies on the original plant to implement the old plant area renovation to maximize the efficiency of resource utilization. Based on the research results of the selectivity test of Xinhai Mining Research Institute, an efficient "two-stage two-closed-circuit grinding, magnetic separation + two-stage reverse flotation" process was designed and implemented to produce ultrapure iron powder with a grade of 71.76% and a recovery rate of 65.36%, as well as high-purity iron powder with a grade of 70.63% and a recovery rate of 30.50%. Xinhai not only completes the full process service from mineral processing test to construction drawing design, equipment manufacturing, installation and commissioning, and worker training, but also provides a one-stop solution for installation materials, electronic control equipment and related tools. During the implementation of the project, Xinhai Mining's innovative technology was combined with refined management to ensure the smooth realization of the construction goals, which was highly recognized by the owner and thanked in a letter.

Xinhai Mining successfully completed the 400TPD gold mine general contracting project in Latin America. The project demonstrated a high level of execution and professional capabilities in design, equipment, installation and commissioning, and automation engineering. According to the high standard requirements of customers, Xinhai equipped the project with international brand equipment such as Siemens motors, SEW reducers, and ABB electrical components, and provided a full set of automated process detection instruments and central control systems. At the same time, the safety and reliability of the equipment are ensured through the all-bolt steel structure design. After the project was successfully completed, the dressing plant carried out a test run with materials, and all indicators performed well. The ore grade was 3-5 g/ton, the recovery rate reached 92%, and the processing capacity was stable at 500 tons per day. At present, the processing plant is operating smoothly and achieving continuous withdrawals, bringing significant economic benefits to customers.
