Description

Verfahren- zum Gewinnen von Mangan aus Erzen durch Auslaugen Durch das Patent 687 o16 ist ein Verfahren zum Gewinnen von Mangan aus Erzen durch Auslaugen mit Schwefeldioxydgasen in Gegenwart von Wasser in mehreren Stufen bekanntgegeben worden. Das Verfahren besteht darin, daß in der ersten Stufe unter Außeracht, lassung der Dithionatbildung soviel Mangan wie möglich ausgelaugt wird und daß in der zweiten Stufe vorzugsweise bei einer Temperatur von 25 bi:s 35° C die in der ersten Stufe gebildete Salzlösung nach Trennung vom Gelösten mit frischem Erz versehen wird, wobei sich das in der ersten Stufe gebildete Dithionat ohne weiteren Zusatz von schwefliger Säure zu Mangansulfat umsetzt und das gebildete Mangansulfat in bekannter Weise auf Mangan bzw. Manganverbindungen weiterverarbeitet wird.Process - for obtaining manganese from ores by leaching by the 687,016 patent is a process for recovering manganese from ores by leaching with sulfur dioxide gases in the presence of water in several stages been. The procedure consists in disregarding the first stage the formation of dithionate as much manganese as possible is leached and that in the second Stage preferably at a temperature of 25 to: s 35 ° C that in the first stage formed salt solution is provided with fresh ore after separation from the dissolved, wherein the dithionate formed in the first stage without further addition of converts sulphurous acid to manganese sulfate and the manganese sulfate formed in known Way is further processed on manganese or manganese compounds.

Die Erfindung besteht nun in der Anwendung dieses Verfahrens auf die Verarbeitung von manganhaltigen- Stoffen, die auch. Phosphor enthalten. Es hat sich gezeigt, daß der Phosphor bei dieser Verwendungsart in Form von Phosphorsäure mit dem Eisenoxyd, der Kieselsäure us.w. in dem Schlamm verbleibt. Diese neue technisch bedeutsame Anwendung des Verfahrens ist auch für stückige Manganerze brauchbar und ermöglicht die Gewinnung einerseits einer praktisch reinen Manganverbindung und anderseits eines Rückstandes, der neben Eisen auch Phosphor enthält und so zu einem wertvollen Phosphorträger für die Herstellung des phosphorhaltigen Thomasroheisens wird.The invention consists in the application of this method to the Processing of manganese-containing substances that too. Contain phosphorus. It has showed that the phosphorus in this type of use in the form of phosphoric acid with iron oxide, silica, etc. remains in the mud. This new technically significant application of the process can also be used for lumpy manganese ores enables extraction on the one hand a practically pure manganese compound and on the other hand a residue which contains iron and phosphorus and so on a valuable phosphorus carrier for the production of the phosphorus-containing Thomas pig iron will.

Sollten bei diesem Prozeß ferner in dem Erzrückstand nennenswerte Manganmengen ungelöst verbleiben, so werden auch diese ausgewertet, da ja das Thomasroheisen um so wertvoller ist, einen je höheren Mangangehalt es hat.Should also be significant in the ore residue in this process Manganese quantities remain undissolved, these are also evaluated, since the Thomas pig iron the more valuable it is, the higher the manganese content it has.

Die Verwendung stückiger Manganerze auf diesem Wege ist dadurch gleichfalls möglich, daß es vorher mindestens unter o,2 mni Korndurchmesser zerkleinert wird.The use of lumpy manganese ores in this way is also possible it is possible that it is previously crushed to a grain diameter of at least 0.2 mm.
