Today is flotation day. International Mining’s July issue, currently at the printer, includes details of many new technologies and ideas in flotation. News that missed the cut is that JKTech has released the next level of capability for its steady state simulator for flotation circuits: JKSimFloat V6.2PLUS. JKSimFloat V6.2PLUS includes a size-by-assay mass balancing capability, in addition to all the flotation circuit simulation capabilities it currently offers. This allows the user to mass balance both size, assay and size-by-assay experimental data from circuit streams simultaneously to produce a consistent data set.

Development of JKSimFloat began in the early 1990s at the JKMRC and incorporated many of the research outcomes from the flotation research at the time. In 2000 development continued under the AMIRA P868 project with contributions from University of Cape Town and project company sponsors and continued until June 2009. Today, over 100 JKSimFloat licences distributed globally are helping mining companies, service providers and educational institutions simulate, understand and optimise flotation circuits.

JKTech’s continuing development of JKSimFloat will next culminate in the release of Version 6.4PLUS to the in August 2011. Additional capabilities available here will include model fitting, liberation data importing and viewing plus the provision of standard data templates.
