China aims to increase self-sufficiency on iron ore with ...

Jul 21, 2021  In light of this, a group of scientists has set the goal to increase self-sufficiency in iron ore. The main reason behind China's dependency on imported iron ore is that the country's iron ore is relatively low-grade and expensive to process. Ever since 35-year-old Sun Yongsheng acquired a doctorate in mining science six years ago, he has ...

Ore Grade Reconciliation Techniques – A Review

The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.

Reduce ore dilution and loss in open pit mines BMT

Ore loss occurs when material containing grade (ore) is incorrectly sent to a waste dump. When a cost is given for Ore Loss, it is the sale value of the metal (gold, copper) recovered from this ore (i.e. ore tonnes x grade x recovery rate x metal price). Dilution occurs when waste is unintentionally with material containing ore and sent to the ...

Relating Iron Ore Lump and Fines Grade Split to Ore Type

When iron ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines grades. Generally the lump product is richer in iron and lower in the other minerals, compared to the fines product. The grade differences between lump and fines, together with the lump percentage, are referred to as the lump algorithm'.

Estimation of iron ore grade distribution has been attempted using geostatistics and artificial neural network (ANN) based models for a banded iron formation (BIF) type iron ore deposit of East India. Geologically, it is a supergene iron ore formation through an enrichment process of parent material (BIFs) by gradual leaching of impurities, namely SiO2 and Al2O3.
