Abstract:
A process where calcium borates are precipitated from an aqueous solution of ulexite is disclosed. The ulexite is dissolved in hydrochloric acid. Calcium chloride then is added to the acid solution and then neutralized to precipitate the calcium borates. The calcium borates so produced are useful as glass forming, batch ingredients that can be compacted into agglomerates and preheated.
