  1. The ore consists of clay, limonite pyrolusite and psilomelane, thoroughly mixed and carried quartz, barytes and gypsum crystallised in cavities. The average grade is 24 per cent manganese. 2. Beneficiation by gravity methods, by flotation or magnetic seperation was unsatisfactory. 3. The possibility of hydro-extraction of the ore was investigated and leaching with Ferrous Sulphate (waste Pickle Liquor) was selected for trial. 4. Overall recoveries of 85 per cent of manganese were obtained in a product assaying 60 per cent manganese. 5. Capital cost of a plant to supply 2000 tons per year of metallurgical grade manganese oxide would be approximately £158,000. 6. The cost of producing this material, after allowance of credit for gypsum and precipitated iron oxide is approximately £28 per ton.
