METHOD FOR MANUFACTURING MANGANESE SULPHATE COMPONENT, APPARATUS FOR MANUFACTURING MANGANESE AND ZINC SULPHATE COMPONENTS, SULPHATE COMPONENT COMBINATION AND USES
The object of the invention is a method, to manufacture a manganese sulphate component from the black mass material (11) of used alkalin batteries (11'). The method comprises a first acid dissolution (201) carried out on the black mass material in the presence of water (12) and sulphuric acid (13) to dissolve zinc (20), potassium (30) and chlorine (35) from the black mass material into a zinc sulphate component (16); a first filtration (202) to separate the zinc sulphate component from a manganese component (15) remaining from the first acid dissolution; a second, acid dissolution (301) carried out on the manganese component in the presence of purified, water ( 12'), sulphuric acid and at least one reducing agent (14) to form a suspension (41) from the manganese component; a second filtration (302) to remove an insoluble solid, matter (26), such as, for example, graphite (27), carbon black (28) and plastic (29), from the suspension to form a process solution (17); a sulphide precipitation (105, 303) and at least one subsequent separation step (106, 304) to remove zinc (46) and copper (21) from the process solution formed, after which the manganese sulphate component (24) formed is suitable for use as a fertiliser (24.1) or as a fertiliser component in agriculture, or as an industrial raw material ( 24.2). In addition, the object of the invention is also an apparatus for manufacturing manganese and zinc sulphate components, a sulphate component combination and uses.

METHOD FOR MANUFACTURING MANGANESE SULPHATE COMPONENT FROM MANGANESE-CONTAINING MATERIAL OF ZINC ELECTROLYSIS, MANGANESE SULPHATE COMPONENT AND ITS USE
The invention relates to a method for manufacturing a manganese sulphate component (24) from a manganese-containing material (11) of zinc electrolysis. In the method the manganese-containing material is dissolved (101, 201, 402) in the presence of water (12), sulphuric acid (13) and at least one reducing agent (14) to form a suspension (25); a process solution (15) is formed from the suspension by separating (102, 202, 403) there from a first precipitate (16) containing at least lead (17) and silver (18); metals and/or metal compounds, including one or more of the following: zinc (20), copper (21), is precipitated (103, 203, 408) from the process solution by using at least one sulphide source (19), and a precipitate (23) containing metal sulphides (22) is separated (104, 204, 409) from the process solution, after which the manganese sulphate component formed is suitable for use as a fertiliser (24.1) in agriculture or as an industrial raw material (24.2). Furthermore, the invention also relates to the manganese sulphate component, the use and the product thereof.

PROCESSES FOR PRODUCTION OF MICRONUTRIENTS FROM SPENT ALKALINE BATTERIES
A process for processing a leach solution of black mass of spent alkaline batteries which leach solution comprises metals dissolved to an acidic solution. The process comprises removing of one or more elements from the leach solution by a cementation operation by applying at least one non-noble metal in a metal form as a cementation agent and one or more additional cementation agents from both sulphate and nitrate groups to process the leach solution into a product of at least manganese- and zinc-containing sulphate solution which is suitable for use as micronutrients alone, in fertilizers and/or together with a plant protective agent to aid growth and health of plants. In addition, the invention also relates to a process for processing a black mass of spent alkaline batteries.
