Dear Tim in Vancouver,

Thank you for your question and for taking the time. 

I assume you are talking about our Drosrite™ system. As mentioned in the article, Jarosite, a basic hydrous sulfate of potassium and ferric iron, is a byproduct during the purification and refining of zinc. However, I would like to point out that there is no zinc in Jarosite.  PyroGenesis’ DROSRITE ™ system is a sustainable process for maximizing metal (aluminum and/or zinc) recovery from the dross generated. Therefore, there isn’t an application for DROSRITE™ for the jarosite residue.

Hope it helps,
