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 completed a 10,000tpd heavy sand ore wet separation production line construction project in Mozambique, covering the raw material system, pulping system, roughing system, scrubbing system, magnetic separation system and selection system. In view of the ore characteristics of local laterite-type and coastal-type zirconium-titanium placers, Xinhai has innovatively optimized the mineral processing process, using "one rough, one fine, one scavenging" and "screw scavenging, sweeping + shaking table selection" etc. technology to ensure efficient separation of zircon titanium ore and silica sand, ilmenite and zircon sand. At the same time, through the "five minus one plus" optimized design, the rationality and economy of the process are greatly improved, the height difference is fully utilized to realize the self-flow of slurry, the equipment configuration is simplified, and the construction and operating costs are reduced. The entire design process strictly follows national standards to complete the multi-professional construction drawing design of mineral processing technology, equipment, electricity, civil engineering, etc. The equipment configuration fully reflects the concept of "maturity, reliability, safety, and environmental protection", and finally achieves the entire line to meet standards and production, bringing customers Significant benefits.
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 successfully promoted the Indonesia 200tph limestone preparation project, providing efficient preparation solutions for customers' mining production. The design of this project covers many professional fields such as general layout planning, mineral processing process design, civil engineering structure, water supply and drainage, ventilation, electricity and automation. According to the needs of the owner, Xinhai designed the process flow as "ore crushing-grinding and classification" to achieve a processing capacity of 200 tons of ore per hour. Within the tight construction period, the Xinhai team ensured the high-standard completion of the project with professional design capabilities and efficient execution.
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 adopts the innovative "crushing + high-pressure roller mill + ball mill" crushing and grinding process in the design, which greatly reduces energy consumption, and reduces the amount of ore entering the mill through the ultra-fine powder ore dry separation process, which reduces the burden of the mill and effectively reduces the pressure of the tailings pond. In addition, in terms of titanium ore separation, Xinhai adopts the "strong magnetic + flotation" process combined with the high-concentration flotation titanium process, with a flotation concentration of up to 50-60%, which improves the titanium selection effect and has stable and reliable technology. The vertical mill is used for the re-grinding of titanium coarse concentrate, which not only improves the grinding efficiency, but also improves the working environment and reduces noise and vibration. The smooth progress of the project has also created local employment opportunities and promoted economic development.
Xinhai successfully completed the Middle East 1200tpd gold mine expansion project, which includes the expansion and installation and commissioning of the first phase 500tpd and second phase 500tpd beneficiation plants, covering the powder silo, grinding workshop, leaching workshop, concentration (water pool) workshop, tailings dewatering workshop and desorption electrolysis workshop and other process links, involving water supply and drainage, electricity, civil engineering and general layout and other multi-professional collaborative design. The beneficiation process designed by Xinhai is raw ore crushing-grinding classification-cyanide leaching-gold-containing precious liquid adsorption-desorption electrolytic smelting-tailings dehydration, ensuring a high gold recovery rate and meeting the strict requirements of customers. During the implementation of the project, Xinhai optimized the pipeline design to ensure continuous production during the transformation, without dismantling existing facilities or stopping production, and without affecting customer revenue. The first phase of construction took only 1 year and 9 months, and the second phase took only 10 months to achieve full production. After commissioning, the processing capacity reached 1,300tpd, and the output and recovery rate exceeded customer expectations. With the advantages of fast construction speed, active response to problems, and stable process operation, Xinhai has won the high trust and recognition of customers.
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.
