A chemical sedimentary rock deposited by precipitation from mineral waters, especially siliceous sinter and calcareous sinter.

1780, from German Sinter, cognate with English cinder.

Mineral deposit formed by evaporating, mineral-rich spring water. It forms when the water comes to the surface and loses its capacity to withhold the dissolved mineral, thereby depositing it and formi [..]

Baked particles that stick together in roughly one-inch chunks. Normally used for iron ore dust collected from the blast furnaces.

This lumpy material is produced by integrated steelworks for use as a raw material in ironmaking, and is the main way of introducing iron ore

roasting of fine–grained ore to produce larger particles for further treatment.

Mineral deposit formed by mineral-rich spring water which comes to the surface and loses its capacity to withhold the dissolved mineral, thereby depositing it and forming a growing mound.

Fine particles of iron ore that have been treated by heat to produce blast furnace feed. Skarn

The coherent imporous mass produced by heating without melting.
