Development of an expert system for iron ore classification

2018-7-27  The grade of the iron ore largely depends on the material type (hereafter referred to as ore type), which provides certain useful information for grade control and grade monitoring. However, in order to establish the ore quality during mining operations, an experienced geologist and a sophisticated analyser are required at the mining site.

IRON ORE1 - USGS

2021-2-4  IRON ORE . 2020 was $84.73 per ton in April compared with the low of $76.16 per ton in January 2019. The prices trended upwards owing to a reduced supply of higher grade iron ore products, spurred partially by closures of pelletizing plants in Brazil. One company in Brazil cut guidance for pellet sales in 2020 by 25 million to 30 million tons ...
