MINCHEM™ & MINCHEM+™

Advanced Circuit Modeling Solutions for the Mining Industry

Modeling is a crucial first step in designing a solvent extraction (SX) circuit. It helps in optimizing plant design to reduce risks and costs, and ensure effective operations. Metal production is more precious than ever as demand for copper and other metals grows, driven by the energy transition, hyperconnectivity and vehicle electrification.

Yet, modeling remains challenging. Complex interactions between chemical processes, fluid dynamics and varying ore compositions present obstacles to creating effective models. For these reasons, sophisticated simulations are needed to improve efficiency and output. Syensqo’s proprietary MINCHEM™ and MINCHEM+™ modeling platforms optimize SX operations by reducing design time, project risks and operating costs.

What are MINCHEMTM and MINCHEM+TM?

MINCHEMTM is a robust modeling and simulation platform specifically designed for solvent extraction operations focused on copper (Cu) modeling with ACORGA® extractants. Its main objective is to optimize existing circuits or evaluate future circuit conditions. With a long legacy dating back to its first release in the 1980s, MINCHEMTM has been a trusted tool in the mining industry for decades. In 2018, MINCHEMTM was upgraded to become the advanced modeling tool behind SolvExtract®, Syensqo’s live SX plant monitoring and optimization platform.

MINCHEM+TM extends the capabilities of MINCHEMTM beyond copper, using CYANEX® and DEHPA® modeling to support the design of new mines and more complex SX circuits. These capabilities have been further enhanced via a full redesign of the models and computational capabilities behind MINCHEM+TM, enabling - just as for MINCHEMTM - computation of reagent requirements and plant parameters in a matter of seconds or minutes.

MINCHEMTM and MINCHEM+TM are based on Syensqo’s leading knowledge in mining and reagent chemistry, which led to the development of the proprietary algorithms that power these platforms. The platforms provide the industry with unique modeling services backed by Syensqo’s expertise in solvent extraction applications.

Optimizing Copper SX Modeling for Current and “What If” Scenarios

MINCHEM™ helps mines make informed, swift decisions that enable circuit optimization and cost reduction. The platform offers quick identification of optimization parameters for both current and future circuit conditions, allowing for a comprehensive assessment of performance and efficient evaluation of process changes. With its fast and reliable computation capabilities, MINCHEM™ can predict plant performance based on a set of parameters, making it an indispensable platform for process engineers.

Key Benefits:

  • Enables fast computation of reagent requirements and plant parameters (seconds or minutes)
  • Facilitates reagent optimization by screening various ACORGA® formulations to ensure the most effective reagent is selected for given conditions
  • Promotes quicker trials by providing accurate stage efficiency calculations, isotherm generation and process change simulations 
  • Reduces CAPEX/OPEX through more efficient modeling, reduced lab work and quicker implementation of optimizations
     

Faster Startups, Better Outcomes: SX Modeling Beyond Copper

Syensqo’s MINCHEM+™ modeling platform optimizes the design of complex circuits for metals other than copper - including cobalt, nickel, zinc, rare earths and more - particularly to support new mine projects. Optimally paired with CYANEX® and DEHPA® reagents, MINCHEM+™ enables fast computation of reagent requirements and plant parameters.  

MINCHEM+™ facilitates integrated modeling of a full circuit - encompassing extract, strip and scrub stages - eliminating piecewise, stage-by-stage testing, and it can handle multi-metal systems with ease. Inputs such as feed composition, reagent type and concentration, and organic/aqueous ratio are used to determine recovery, selectivity, purity, scrub efficiency and pH profiles.

Key Benefits:

  • Enables fast computation of reagent requirements and plant parameters (seconds or minutes)
  • Facilitates the testing of new flowsheets, supporting evaluation of different design options before implementation
  • De-risks projects by identifying potential challenges early on, accelerating project delivery 
  • Reduces CAPEX/OPEX: limits lab work, over design and provides better direction for pilot testing while supporting quicker startups
