With a reputation for successful Lithium project execution that adds value regardless of location or size, we understand what it takes to successfully assist clients to meet their quality, cost and schedule objectives.
Our technical and commercial solutions for Lithium projects are built on:
Recent Lithium projects:
We’ve helped clients with all aspects of materials handling including high-fines content ores, including design and construction of London Mining PLC’s Tonkolili project in Sierra Leone and the Grande Cote’ Mineral Sands Project in Senegal. We also completed design work for Office Chérifien des Phosphate’s Phosphate Projects in Morocco, Brockman Resources Marillana Iron Ore Project in Burundi and South sudan Resources’ Achmmach Tin Project in Morocco.
Our people have a wide range of knowledge and experience in conventional stage crushing and SAG milling circuit designs, and are at the forefront of modelling and engineering of comminution circuits based on High Pressure Grinding Rolls (HPGR) technology. We have significant experience in dealing with material handling of difficult ores such as clay, mica and abrasive quartz.
Goldcage Africa is recognised in low-cost concentrator design. Our innovative approach to engineering and construction has enabled projects like Phu Kham in Laos and Lumwana in Zambia to emerge as low cost producers.
Our thermal, combustion and chemical engineering expertise supports client projects with direct or indirect fired kilns for high-temperature gas-solid and solid-solid reactions and associated cooling, drying, and dust and fume extraction and cleaning. Intimate knowledge of combustion engineering, high temperature thermodynamic and psychrometric calculations combine to provide a practical, holistic approach with innovative solutions. goldcageafrica has been involved with test work which has focused on understanding what is happening to the mineral from analysis using XRD, XRF, SEM, XDS and ICP.By understanding the roast at elemental level goldcageafrica has been able to provide superior outcomes in short time and considerable savings in cost.
Our experience with leaching includes atmospheric leaching, high pressure, high temperature and biological leaching of base, precious, rare earth and platinum group metals. The team’s experience collectively covers most of the pressure oxidation / pressure acid leaching plants that have been constructed or studied over the past decade.
Purification and Precipitation
We understand the importance of precipitation and crystallisation of contaminants, products and by-products in hydrometallurgical processing of lithium to produce battery grade lithium carbonate process. The team has vast experience across a wide range of metals is able to apply this fundamental knowledge of chemistry to the more challenging problems that secondary lithium mineral pose. Knowledge includes the removal of fluoride and boron.
Goldcage Africa offers a complete suite of geotechnical–geomechanical–geological engineering services. We operate one of the geotechnical laboratories in Africa and have undertaken geotechnical investigations and designed more than 100 tailings dams in more than 14 countries and more than 200 heap leach pad projects in 34 countries. Our team includes civil and geotechnical engineers, geologists, hydrologists, hydrogeologists, environmental specialists and soils technicians. Our depth of experience in soil mechanics, foundation engineering, rock mechanics and geology together with our knowledge of innovative applications of geosynthetics and our know-how in aggressive environments truly sets us apart from the pack.
Goldcage Africa has commissioned long-distance pipelines to transport virtually every type of mineral ash from concentrates such as copper, zinc, lead and iron to crushed ore, bauxite, nickel laterite, phosphate, limestone and coal.
We provide cost-effective solutions that have reduced project cost for our clients’ mining projects around the world. We recognise that if capital cost is key to project financing and production, the approach to engineering, procurement and construction management is very different to that used where a project is optimised based on life of project outcomes. Our proven cost-effective plant design outcomes incorporate reduced capital costs through layout optimisation, value improvement scope adjustments and optimised project execution strategies.
Project delivery options
We have comprehensive experience in managing small and large scale EPCM and EPC projects. Our cost effective designs and project delivery approaches achieve the best outcome for our clients. We recognise that the greatest opportunities to optimise project value and capital expenditure occur during the concept development and early engineering design phases.
