Research & Development Focus


Our in-house R&D laboratory develops tailor-made products and grades for varying customer needs. We are currently involved in important development projects in the lithium-ion battery industry with ultra-fine Manganese carbonates, in the water treatment domain with very efficient manganese dioxides which absorb toxic substances, and also high surface area manganese dioxides geared towards organic chemical markets.

Further to these ongoing developments, we commit ourselves to be the most active manganese chemicals supplier, producing Mn-based chemicals for tomorrow.

Baltimore offers top of the class reliable manganese chemicals supplies. This reliability is also insured by stringent maintenance standards which allow uninterrupted supplies. In addition, this ore is naturally low in heavy metals and other impurities.

In line with Prince Erachem's sustainable development approach, the Baltimore plant has developed processes which preserve natural resources (water, air, soil). Baltimore also continuously develops ways to optimize yields and reduce energy consumption. We protect and develop our employees, putting safety first. Thus the plant has not suffered from any accident with lost workdays for over three years.
