Title : Planet Positive Technologies and Systems for the Mining Industry

Abstract : The mining industry is facing a dual challenge. More metals and industrial minerals are needed for the transition to a low carbon economy and, as a part of it, a fast “batterisation”. On the same, the permitting has become much stricter. The old sins of the mining industry essentially deny the social license to operate.
Solving the dual dilemma requires some new thinking. 
Understanding that the whole value chain of converting mineralization to value for all the stakeholders is systemic is a good starting point. The existing compartmentalized optimization will not give us the advances we need to solve the two significant challenges.  We need to know the interactions within the system when we design new processes and production equipment. The systemic structure is discussed in the plenary.
Metso-Outotec has set its targets to have all its new products and process solutions ”Planet Positive”, meaning that everything is designed to reduce energy (CO₂ emissions) and use of water, reagents and other consumables.
Some Planet Positive equipment developments are discussed in detail, especially the next generation high pressure grinding technology offering substantial reductions in CO₂ emissions.
A major thrust is given to achieve a “Zero Effluent Plant”. It requires a deep understanding of some scientific aspects of mineralogy, mineral surface chemistry, and water chemistry. These are necessary to modify the whole process chain towards the target. The system solution development and the required technologies are discussed.
