Belt pressing or other pressure dewatering of a high solids mineral suspension is facilitated by flocculating the suspension by mixing into the suspension anionic flocculant having IV at least 5 dl/g and a minor amount of a cationic flocculant which generally has IV at least 4 dl/g. The flocculants are normally such that counterionic precipitation occurs.
