Extensive work has gone into designing the most efficient and cost-effective processing route for producing lithium hydroxide from ore. We use non-toxic additives and our low-waste process is designed to ensure that as much as possible of what comes out can be used commercially to support local industries.

The Zinnwald advantage 

 Zinnwaldite is a type of ore first discovered in Saxony in 1845. As a source of lithium, it is more environmentally friendly to work with than the more commonly mined spodumene ore. In processing, less heat is needed in the calcination stage, and the leaching stage can be done using water instead of acid. 

Notably, various parts of our overall flowsheet use well-established techniques from other industries, but are packaged together into one flowsheet for the first time.

Potassium carbonate is commonly used in the production of soap and glass and is a good source of potassium, which is an essential nutrient for plants.
