DE2159364A1 Manganese iron mixed oxides with haematite

mixed oxides, for use as temp. stable black pigments with a high degree of colouring power, are prepd by grinding together beta FeOOH and a 2.63 valent Mnoxide. This mixture is heated at 800 degrees C and yields a product with haematite structure and a Mn/fe atomic ratio of 10/9055/45. The Mnoxide is pref. Mn3O4 or gammaMnOOH, produced in situ by redn. of pyrolusite or a divalent MnCpd.

Optimizing Soil Grinding to Measure Soil Manganese Content

Soil types such as; manganese dissolved in water, manganese oxides, manganese in pyritecontaining shale, a control group with sand and peat were tested. My role began with grinding soil samples into a specified ( 15g) mass, to allow the fine fragments of soil to fit through a 75m sieve.

Manganese phosphate coating on steel issues and answers

Manganese phosphate coating on steel issues and answers

It is a conversion coating process and involves the dissolution of the base metal which subsequently forms part of the coating. In manganese phosphate coating the species that deposits on steel is manganese iron phosphate and hence requires a large amount of metal dissolution so that the formation of manganese iron phosphate is possible.

Strengthening pelletization of manganese ore fines

Strengthening pelletization of manganese ore fines

Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature elevation system were investigated to improve the
