Minsol Limited operates from Birkenhead and produces bentonite, coaldust substitutes and chromite sand used for metal casting and refractories as well as manufacturing bentonite for other companies which supply civil engineering, directional drilling and industrial markets.

Minsol currently turns over about 30,000 tonnes annually and employs 18 staff. Two of the executives, Phil Mealor and Tony O'Reilly, continue to run the day to day operations at Birkenhead since the acquisition. "Joining the Francis Flower Group is a very positive development for Minsol with synergies between the businesses and the strength of the Group providing growth opportunities" according to Phil, who added "In the coming months we look forward to build on our successes and to getting to know and work with as many people in the Group as we can".

Foundry Minerals, in an allied area to Minsol, imports, processes and markets foundry bentonites used in foundries for green sand moulding and high volume small/medium iron castings. Turnover is around 4,000 tonnes per annum for such applications as gratings and inspection covers, automobile castings, brake discs and railway castings.
