In order to optimize a mineral processing plant there are nine steps required: 1. Collect data (measurement) 2. Collate data (into a database) 3. Flowsheeting 4. Mass Balance 5. Inference 6. Determine Operational Parameter 7. Model fit 8. Simulate 9. Optimise Mass balancing is often taught using least squares minimization. Inference is generally not taught […]
Uranium is known to occur in over 200 different minerals but most of these do not occur in deposits of sufficient grade to warrant economic extraction. Uranium ore can be extracted by open pit, underground or in-situ mining methods. Uranium mill process flowsheets and unit operations for yellow cake production vary based on chemical and […]
Water is fundamental to mining and mineral industry and widely used for processing and treatment, heating, cooling, dust suppression, etc. Managing water and effluent discharge quality throughout the mine life is key to efficient mining and has a big role in mining environmental impact and footprint. Treatment technologies often must deal with regulatory requirements, environmental […]
More than 90% of quantitative professionals (inclusive of Engineers, scientists and analysts) use Excel at a basic level. Yet possibly less than 10% would have received any guidance on how to use Excel effectively. Hence many professionals use Excel in a manner that much of their work is not shared effectively with their colleagues leading […]

Manufacturing process in steel industry undergoing changes for making steel better and better in terms of quality, cost & efficiency. Advance melting techniques like Ladle Metallurgy play an important role in this direction. The focus is to get steel of higher strength/weight ratio along with longer life. This has enabled designer to make product with […]
The metallurgical testwork program is generally the most important critical path item for process design of a circuit and if it is not implemented in a well-structured and framed way by an experienced subject matter expert it can become the main reason of a mining project fatal flow. Not two ore bodies are the same. […]
Gold is among the first metals used by man because it naturally occurs in its native state. Over the years different process flowsheets have been developed with the purpose of optimising gold extraction from a particular feed material using the most appropriate technology. Due to numerous factors ranging from technical e.g. geological, mineralogical, metallurgical and […]

American Exploration & Mining Association (formerly known as the Northwest Mining Association until 2013) is a 122 year old, 1,900 member, non-profit, non-partisan trade association based, in Spokane, Washington. AEMA members reside in 42 states and are actively involved in prospecting, exploring, mining, and reclamation closure activities on USFS administered lands, especially in the West. […]
Mineral processing can involve four general types of unit operation: • Comminution • Sizing & Classification • Concentration • Dewatering Knowing the fundamental principles, conventions and terminology in mineral processing, and having broad overview of current technical and operating issues and circuit design considerations are essential for engineers, technicians, operators, support staff such as accountants, […]
