Here it was demonstrated that when sponge iron was added to a launder, the particles of iron collected in the bottom of the launder and tended to cement together. This resulted in incomplete precipitation of the copper and inefficient utilization of the iron.
The production of raw cement involves the extraction and procurement of raw materials like limestone and clay or iron ore. These materials are then crushed and finely ground to form the raw mix. The raw mix is then subjected to high-temperature heating in a kiln, reaching temperatures around 1400°C in a process called clinker.

The cement manufacturing process involves the extraction and processing of raw materials, such as limestone, clay, and shale, which are then heated in a kiln at high temperatures to form clinker.
Companies are trying to squeeze everything they can from their plants to achieve higher throughputs with minimal spending. Ore grades are declining, pulling product liquor solution (PLS) grades lower, too. Higher flows must be pushed through solvent extraction to maintain production levels at the plant. This can increase entrainment problems.
The plant quality targets for cement making can include several parameters such as directly measured minor constituents like MgO, SO3, R2O, etc. and other critical modulus values.
