Silico manganese alloy recovery from silico manganese slag

Silicon manganese smelting slag is produced when smelting manganese. There are lots of alloy granules mixed in the slag discharged. A certain profit can be gained from recovery of these silicon manganese alloys. Also the scientific treatment for this kind of slag can avoid damage to environment and human health.

Dry Slag


Water-Granulated Slag

To recover  the silicomanganese alloy granules needs the liberation of the alloy from the slag, which requires the further crushing or the milling of the slag according to the specific situation of slag. If the embedded size is very fine, rod milling or ball milling will be considered while crushing shall be chosen when it comes to the coarse embedded granularities, and high-efficiency crusher or fine crusher can be ok to fulfill the requirement.

Silico Manganese Alloys

In the crushed or milled silicon manganese smelting slag, the alloy granules and the waste are separated or liberated. The silico-manganese alloy granules are of high density while the density of the waste is lower. With this difference, gravity separation will be a ideal way to separate the alloy out. And the alloy granules can be used for smelting or sold directly while the final waste can be sold to the cement factory or new-type building material factory.

The high-efficient machine for this silicon manganese slag is jigging machine. As kind of gravity separation machine, it works on the basis of the different densities of the mineral and tailings, and the bigger the difference is, the better the efficiency it will be and the larger the treatment capacity will be. The following picture is about the examples of successful recovery of silicon managnese alloys from slag.
