Mine-to-metal capability across a range of commodities.
Our clients are building and operating some of the world’s most technically challenging projects in highly demanding environments.
Providing support across a wide range of capabilities, plant capacities and metal production, Jacobs delivers complete solutions to develop, expand and treat simple and complex ore bodies, including non-ferrous sulfide and oxide minerals such as copper, lead, zinc, and nickel.
Each project has its own unique set of challenges, whether it requires significant skilled construction resources, innovative materials handling and procurement strategies, or creative thinking around environmental management and sustainability requirements. Jacobs is always looking for ways to help its clients grow, expand, and innovate.
Globally, Jacobs provides its clients with pit to port capabilities, involving designing and developing the mine and port infrastructure, including the materials handling and processing of the ore. The latter includes copper and polymetallic concentrators; and a variety of smelting projects, from grassroots facilities to retrofitting existing smelters. Experience spans all major unit operations: gyratory, jaw and cone crushers; rod, ball, and tower mills; fully and semi-autogenous grinding mills; conventional and column flotation cells, thickeners, and filters.
Jacobs' nickel and cobalt project experience includes: ore beneficiation, concentrators, pressure acid leach (PAL), heap leaching, pressure oxidation (POX), sulfide precipitation, hydroxide precipitation, hydrogen reduction, Caron process, smelters, solvent extraction, and electrowinning plants.
Working across a range of lead production projects, Jacobs designs, builds, and commissions sinter plants, sulfuric acid plants, lead smelters, and lead refineries which use the latest systems to provide recovery of by-products.
Jacobs' project experience includes both the electrolytic zinc process and the imperial smelting process. We also help clients recover zinc from secondary sources such as lead blast furnace slag, zinc ashes, steel furnace dust, and calcine leach streams.
Flexible capacity – anywhere it’s needed.
By integrating project teams into its clients' business, Jacobs truly aligns with their strategic priorities. Creative planning and new ways of designing and implementing facilities are becoming increasingly essential, as clients look to increase the productivity of their existing mining operations, or research and develop new long-life facilities.
Jacobs designs, constructs and commissions small to large capacity concentrators in the geographies where our clients need us. We help reduce plant area by utilizing large capacity equipment. We optimize process routes, and continuously search for cost-effective construction materials and techniques.
Jacobs delivers complete ore processing facilities, for precious metals projects including gold, silver, and platinum, across a wide range of plant capacities and metal production rates. Ores treated include both free milling and refractory (including roasting, pressure oxidation and bioxidation processes). Many recent gold projects for our clients have involved primary crushing followed by semi-autogenous grinding and ball milling.
Exceptional service through the life of a project.
Jacobs has developed a deep understanding and capability across the unit operations needed for the processing of potash, soda ash, phosphates, borates, mineral sands, and other evaporates.
A feasibility study may grow to technology implementation, detailed engineering, procurement, construction management, and infrastructure. As the complexity of the projects increase we draw on our minerals expertise, as well as experience in large industrial projects, to help clients execute their development and expansion plans.
Jacobs' services in the industrial minerals area include:
- Material handling
