Frequently Asked Questions (FAQs)

How do your vessels address the extreme abrasion challenges in minerals processing applications?

Our vessels designed for minerals processing incorporate several key features to manage abrasion and extend service life. We utilize specialized materials selected for their hardness and wear resistance, implement strategic wear plates in high-impact areas, employ specialized hard-facing and overlay techniques with comprehensive quality verification, and conduct detailed flow pattern analysis to identify and protect vulnerable areas. For particularly abrasive slurries, we employ additional design features such as replaceable wear components, optimized geometry to reduce impingement, and specialized rubber or ceramic linings. Our material selection process considers not only the primary ore characteristics but also variations in particle size, solids concentration, and flow velocities to ensure long-term performance even as mine conditions evolve.

What materials are most suitable for pressure leaching and aggressive chemical processing?

Material selection depends on specific operating conditions, but common choices for aggressive leaching environments include 316L/317L stainless steel for moderate conditions, Hastelloy C-276 or C-22 for extreme acid service, titanium for specific acid mixtures, and specialized alloys like Alloy 20 or 904L for sulfuric acid applications. For cyanide leaching, rubber-lined carbon steel often provides the best balance of performance and cost. Each vessel is evaluated based on its specific chemical environment, temperature profile, pressure requirements, and slurry characteristics. For critical high-pressure acid leaching (HPAL) or pressure oxidation applications, we often conduct specific material testing or reference previous performance data to optimize material selection for the exact process chemistry.

How do you ensure vessel integrity for high-pressure, high-temperature autoclave applications?

For autoclave and pressure leaching applications, we implement comprehensive design and quality measures. Our approach includes detailed stress analysis including consideration of thermal gradients and cycling, specialized material selection with appropriate high-temperature allowances, enhanced non-destructive examination of all critical welds, and detailed design reviews specific to HPAL service. For gold pressure oxidation or nickel HPAL autoclaves, we incorporate features such as specialized brick or lead lining systems, enhanced closure designs for frequent access, and comprehensive thermal expansion accommodation. Our quality control program includes additional verification steps for these critical vessels, and we often implement enhanced post-fabrication testing to validate design calculations and ensure safe, reliable operation in these demanding applications.

What considerations are made for vessels handling variable ore characteristics?

Vessels designed for processing variable ores incorporate several adaptability features. These include adjustable internal components that can be modified as ore characteristics change, enhanced agitation systems that can handle varying solids concentrations, versatile inlet designs that accommodate changing particle size distributions, and material selections that provide a wide operating envelope for varying chemical conditions. For operations processing multiple ore types, we design for the most demanding conditions while incorporating features that optimize performance across the entire range. Our engineering team works closely with metallurgists to understand ore variability projections and incorporates this understanding into designs that remain efficient even as mine conditions evolve over the life of the operation.

How do you address remote location challenges for mining equipment?

We understand that mining operations often exist in challenging, remote locations. Our approach includes several strategies: modular design approaches that facilitate transportation on difficult roads, designs that consider standard shipping container limitations, strategic break-points that allow for field assembly of larger vessels, and comprehensive documentation for local fabrication or assembly teams. For international mining operations, we coordinate with shipping specialists to ensure designs comply with local import requirements. Our documentation includes detailed assembly instructions for field teams, and we can provide remote technical support during installation. For extremely remote locations, we offer enhanced spare parts recommendations and can design vessels with additional inspection and maintenance features to support operations in areas with limited access to specialized services.
