manganese sinter process

What are manganese ore fines and how are they sintered?

Dec 18, 2017  Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become “agglomerated”). “The mines produce a lot of fines,” Hockaday explained. “But they can’t sell them, as furnaces won’t buy materials that are too fine.”

Abstract. In its most basic form, the process of sintering is very simple, and has been in use since the turn of the previous century. However, while the basic process is simple, control of the process relies on a number of extremely complex interdependent process parameters and requires a thorough understanding of the effect of these parameters on production capacity and product quality.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...

Sintering - Wikipedia

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as part of a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the ...
