SERVICES
Metallurgical Pilot Plants
For the six years of existence of the firm, we have offered specialist metallurgical pilot plant services to Tanzania mining industries and beyond our borders. We do not just offer specialized and execute process designs of various metals but also optimize existing plants to increase the productivity of the plants. Nesch Mintech Laboratory has successfully mounted and run numerous pilot plants including a 5 tph continuous grind-hydrometallurgy metal recovery pilot plant. It is a handful task to operate pilot plants at set standards. At Nesch Mintech Laboratory you are guaranteed that all testing will be carried out professionally in advanced pilot facilities. The firm will carry out full design and modelling work ahead of pilot programmes to demonstrate a feasible design and control strategy prior to commencing construction. Nesch Mintech Laboratory’s expertise in the design and execution of these pilot plants drastically de-risks Definitive Feasibility Study (DFS) programmes for our clients.
Clients’ samples are regarded as gold at Nesch Mintech Laboratory, we guarantee that the program will deliver the design criteria output and confidence required for a successful DFS.
Pilot Crushing and Milling
Nesch Mintech Laboratory’s sample preparation facilities are capable of handling several tonnes of rock or sand material. The firm has various sizes of crushers and pulverizes to obtain various particle sizes from larger rocks and sand. Sample preparation is usually carried out amazingly fast to ensure that the test work is done on a short timeline.
Pilot Flotation and Beneficiation
Nesch Mintech Laboratory has a wide range of pilot grinding and flotation equipment available for the execution of an integrated pilot flotation program, including both conventional and Jameson and column cell flotation.
The firm also offers screening and magnetic separation capabilities for beneficiation pilot programmes. Our valued network partners assist Nesch Mintech Laboratory in ore sorting and testing.
Pilot Hydrometallurgy and Leaching
Nesch Mintech Laboratory specialises in pilot plant trials of complex hydrometallurgical processes. Nesch Mintech Laboratory’s expertise in the design and execution of these pilot and demonstration plants significantly de-risks DFS programmes for our clients. Our senior pilot management staff have backgrounds in commercial due-diligence, in addition to their technical hydrometallurgical backgrounds, ensuring pilot programmes have a strong focus on driving out technical parameters and design criteria that will withstand scrutiny from bankers and other stakeholders.
A Pilot Design Package is prepared ahead of each pilot plant, based on process METSIM models, specifying all physical equipment and software systems, operating procedures, sampling schedules and data management and reporting routines. Nesch Mintech Laboratory has developed sophisticated dynamic modelling tools to enable evaluation and review of pilot flowsheets ahead of their construction and execution. This modelling is pilot specific and reflects the subtle differences between a full-scale plant and a demonstration or pilot plant.
Nesch Mintech Laboratory’s knowledge of metal solution chemistry ensures that our process engineers and analytical chemists unlock an understanding of the steady-state chemistry achieved in pilot plants. Our process engineers work hard to identify the effects of impurity build up with recirculation and address their implications during the execution of pilot plants.
Pilot Metal Recovery
Metal recovery is carried out mainly through solvent extraction, electrowinning, precipitation and crystallization. All these services are all offered by Nesch Mintech Laboratory as per client final product specifications. After successful generation of the final product from the pilot trial, clients can effectively market and sell their projects to investors and consumers.
