OLI lithium chemistry simulation

OLI at EXTRACTION 2018

think simulation | getting the chemistry right

OLI Systems will be exhibiting at booth #308 at EXTRACTION 2018. We will be joined by our Alliance Partner, SysCAD (booth #306) as well as our OLI Consulting partner, Mike Dry of Arithmetek. Many other key OLI clients and university partners will attend as well.


Our theme for the conference is "Make OLI your strategy for mineral ore processing" Stop by and get some of our technical papers that explain how.

Also, we can arrange consulting sessions with you during the conference to show how OLI simulation can transform your own current water chemistry processes.

Two papers of interest that you can request from OLI:

   

Extraction of Lithium from Brine - Old and New Chemistry
Author:    Mike Dry, Arithmetek, Inc. Canada 

The following abstract describes the presentation that Mike Dry, president of Arithmetek, Inc. Canada  will make at EXTRACTION during the Processing of Critical Metals - Critical Materials - Lithium session on Monday morning, 27 August 2018. Mike is an OLI Consulting Partner.

Conventionally, lithium-bearing brines are processed via solar evaporation, chemical purification and either electrolysis to lithium hydroxide, or the precipitation of lithium carbonate. Current interest in the lithium-ion battery is forecast to greatly increase the demand for lithium, but many lithium-bearing brines are not easily amenable to the conventional extraction process and new approaches are being developed. This paper will review the chemistry of selected brines currently being processed and some brines targeted for processing that are not amenable to the conventional route. The process chemistry associated with the conventional lithium extraction route and a number of the new approaches will be outlined and explored. The focus will be on what makes some brines bad candidates for conventional processing and how the new approaches are attempting to overcome that which makes conventional processing unsuitable.

Modelling Solvent Extraction as a Chemical Equilibrium 
Author:    Mike Dry, Arithmetek, Inc. Canada 

The following abstract describes the presentation that Mike Dry, president of Arithmetek, Inc. Canada  will make at EXTRACTION during the Gordon Ritcey Symposium: Advances in Hydrometallurgical Solution Purification Separations session on Tuesday morning, 27 August 2018. Mike is the chairman of this session.

Solvent extraction is often modelled via loading, scrubbing and stripping isotherms. These isotherms are measured by laboratory work, each species to be extracted requiring its own isotherms. Apart from single species McCabe-Thiel plots, translating these isotherms into process predictions entailing the extraction of any given species from a feed containing more than one species that can be extracted is not within the normal capabilities of those who must design overall circuits. This paper will present a methodology for modelling solvent extraction as chemical equilibrium reactions between the various aqueous and organic species when more than one extractable species is involved. It will cover the extraction of the relevant parameters from standard laboratory tests measuring individual isotherms and show how these parameters can then be used to model continuous solvent extraction. Examples will be presented for a single-reagent extraction and for synergistic solvent extraction.
