· A serious problem faced by the metal mineral mining industry is the challenge to the sustainable development of resource mining due to the continuous decline of ore geological grade. In the case of producing concentrates of the same quality, compared with using only high-grade raw ore, ore blending is a way to slow down the decline of ore …
Ore Blending is an important problem that the majority of mining enterprises have to face. To solve the ore blending problem, the production plan should be made firstly, and then small adjustments should be made in according to the actual condition. By effective control and management, the balance of ore quality and stability will be realized.
The invention provides an ore blending structure evaluation method based on granulation quasi-particle sintering behavior, which relates to the technical field of ferrous metallurgy, can intuitively know the quality of liquid phase fluidity of sintering raw materials with different proportions under sintering production granularity, and determines the optimal ore …
· Recent research has fueled an emerging interest in blending on physical ore properties as well. Fully autogenous mills rely on the large, competent fraction of crushed feed to act as grinding media. Previous test work indicated that Hibtac mills require specific amounts of 6- to 10-inch ore.

· An evolutionary algorithm-based methodology has been adopted for ore blending to maximise the total manganese content of the ore blend under applied physico-chemical constraints. Analysis provides various blends of the same chemical composition but of different geometallurgical ranks. An artificial neural network model has been …
· For production cost reduction, optimised blending ratios were designed according to ore prices and properties (microstructure, crystal water decomposition, assimilation ability, liquid phase fluidity), ensuring nearly identical chemical composition as the mixture used in actual sintering.
· Three test pads were used to assess different blends to get to the two blending strategies that they use today: blend soft advanced argillic clay ore at a 1:1 ratio with harder run-of-mine clay ore and blend the very soft extreme argillic clay ore at a 1:1 ratio with run-of-mine rock ore. The blending occurs as it is stacked onto the leach pads.
