Indonesia is one of the world's largest nickel producers, with nickel ore production reaching 1.6 million tons in 2022, accounting for 48.8% of the world's nickel ore production. Indonesia's laterite nickel ore resources are not only rich in reserves and high in grade, but also have an advantage in geographical location. The development of tailored laterite nickel ore dressing solutions has enabled Indonesia to occupy an important position in the global nickel market.
However, we found that some mining rights holders, although they have the mining rights of laterite nickel ore, lack a complete mineral processing technology system. As a global mining service provider, Xinhai Mining can provide customers with mining industry chain services (EPCM+O), which can solve the whole process delivery from mining to primary processing. It provides a turnkey solution of "mine design-ore dressing line construction-equipment complete set supply" and bundles equipment maintenance agreement.
Are you troubled by these problems?
❗️ The international EPC contractor's quotation exceeded the budget by 40%, but the equipment maintenance has to wait for 3 weeks?
❗️ The moisture content of laterite nickel ore is as high as 35%, and the crusher is shut down for cleaning 3 times a week?
❗️ The mining license extension was rejected because TKDN's localization rate did not meet the standard?
❗️ Environmental regulations are becoming more and more stringent, how to deal with wastewater discharge and land reclamation?
Xinhai Mining: It can be realized for Indonesian mine owners through EPCM+O solution——
✅ Nickel recovery rate 88.7%
✅ Equipment operation and maintenance costs dropped by 32%
✅ 100% passed the ESG audit of the Ministry of Energy and Mineral Resources
✅ Tailings treatment was completed simultaneously to ensure environmental protection standards are met, and tailings can be reused
Xinhai EPCM+O model is a mining industry chain service model that covers the entire life cycle of mining projects, including Engineering(E), Procurement(P), Construction(C), Management(M) and Optimization(O). This model is committed to providing customers with a one-stop solution to ensure that the project reaches production targets according to budget investment and planned construction period, and maximizes customer benefits.
Advantages of Xinhai EPCM+O
One-stop service: Covering the entire life cycle of mining projects, providing integrated solutions from design to operation.
Professional Team: Possessing Class B design qualifications in the metallurgical industry and a wealth of professional design talents.
Smart mines: Promote intelligent and unmanned solutions to create smart and green mines.
Construction capabilities: Possess first-class qualification for general contracting of mining engineering construction, and be able to undertake large and complex mining engineering projects.
High-pressure acid leaching process (HPAL): Applicable to laterite nickel ore in limonite layer. The process is carried out in an autoclave, using sulfuric acid as the leaching agent, with a reaction temperature of 245-270℃ and a pressure of 4-5 MPa. The advantage of this process is that it can effectively treat low-grade laterite nickel ore with high cobalt and iron content, but the equipment requirements are high and the investment cost is large.
Normal pressure acid leaching process: Applicable to laterite nickel ore in transition layer. This process is similar to high-pressure acid leaching, but it is carried out at normal pressure, with lower leaching efficiency, but relatively lower equipment requirements.
Reduction roasting-ammonia leaching process: Applicable to laterite nickel ore in humus layer. This process includes two steps, reduction roasting and ammonia leaching, which can effectively recover nickel and cobalt, but the process flow is complicated and the energy consumption is high.
1. Customer dilemma
- Ore processing capacity: 500,000 tons/year (mining rights facing cancellation)
- Nickel recovery rate: 72%
- Equipment failure rate: 12 times per month
2. Xinhai intervention plan
Install slurry preheating system → HPAL acid consumption reduced by 15%
Deploy AI ore sorting machine → Waste rock rate reduced from 40% to 18%
3. Quantitative results
Annual processing capacity increased to 1.4 million tons
Investment payback period shortened to 2.3 years
Won the title of "Green Mine Demonstration Project" by the Ministry of Energy and Mineral Resources
