Dry beneficiation of iron ore
The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.

Wet Milling vs Dry Milling: The Differences, Advantages, and Challenges
Products can be broken down through either one of these processes, but wet milling, which we'll discuss first, tends to be a more intensive process than dry milling. Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing.

Understanding the Distinction: Wet and Dry Processing …
The primary distinction between wet and dry processing methods lies in the drying stage. Dry processing relies solely on the sun's heat to dry the cherries. This natural drying process can take significantly longer than the wet processing method. The cherries may need to dry for weeks or even months, depending on the climate.

Mineral Processing – Can We Keep It Dry?
Is dry grinding possible. Wet grinding is currently the most common method for particle size reduction and mineral liberation. However research is being done on the future application of dry grinding. The current studies indicate that dry grinding consumes higher energy and produces wider particle size distributions than with wet grinding.
