Operations | Anglo American – Kumba Iron Ore
The ore quay at Saldanha has two berths where two vessels of 310,000 deadweight tonnage can simultaneously tie up at the iron ore jetty. The terminal operates 24/7 and has the capacity to offload 10,000 tonnes per hour onto a vessel. From arrival to departure an ore vessel carrying 170,000 tonnes will be in Saldanha Bay for just 24 hours.

Extraction of Iron | Metallurgy | Blast Furnace and Reactions
The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A blast furnace is a gigantic, steel stack lined with ...
A simple image-based method for online moisture content …
Moisture content (MC) is an important quality metric of iron ore green pellets in pelletizing process in ironmaking industry. Current image-based methods for MC estimation may result in big errors for gray-scale pellet images captured under various lighting conditions. We proposed a simple image-based method to improve the MC …
