Description / Location
Chemionex was formed in 2005. Since that time we have worked with dozens of companies to solve their chemical separations problems.
In addition to its in-house expertise and resources, Chemionex has a vast network of contacts, accumulated over forty-five years in the field, whose knowledge we can draw on. We work extensively with outside laboratories and consultants as the need arises. In fact, many of these companies utilize Chemionex to expand their expertise.
Chemionex is located in Pickering, Ontario, on the eastern border of Toronto, Canada. Highway 401, the nation’s largest thoroughfare, is at our doorstep. Pearson International Airport is a half-hour drive and we are located close to the ‘GO’ commuter train with hourly service to downtown Toronto.
Hydrometallurgical and Chemical Separations
Chemionex are experts in the field of hydrometallurgical and aqueous based chemical separations. We use technologies such as ion exchange, membranes, electrodialysis, electrolysis, evaporation and crystallization to separate dissolved metals, acids, salts and organic materials in aqueous solutions.
After a careful evaluation of your application, we will work with you to devise a process to achieve your objectives. Sometimes this involves merely a consultation or survey of the technical literature. In many cases testing is conducted in Chemionex’s well equipped laboratory on simulated or actual process solutions to develop or evaluate a particular process.
We can even provide pilot plant equipment on a rental basis, so that the process can be evaluated in your plant over an extended period of time. Once a process has been developed, we will partner with an appropriate equipment vendor to design and manufacture equipment and integrate the process into your operation on a full industrial scale.
