Review of organic binders for iron ore concentrate agglomeration …
Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make …

The agglomeration of nickel laterite ore
The agglomeration of nickel laterite ore ... The lateritic nickeliferous iron ore deposits of Central and Northern Greece (Euboea, Locris, Boetia, and Kastoria) provide the feed material for the production of an iron-nickel alloy at a pyro-metallurgical plant located in Larymna. Due to the low quality of the feed ore, about 0.90-1.00 % nickel ...
Effect of ore types on high temperature sintering …
The ore type of adhering fines and substrates affected the penetration and assimilation ability of the initial melt, but a good formation ability and fluidity of initial melt was the basis of good penetration and assimilation ability. Based on the micro and macro sinter structure, the high temperature characteristics were further related to the ...

The experimental agglomeration refers to the procedure of using chemical binders to adsorb and bond crushed ores and fine powders to form wellshaped agglomerations (WAs), which could obviously ...
Agglomeration and leaching behaviors of copper oxides …
The chemical binder is one of the critical factors affecting ore agglomeration behavior and leaching efficiency. In this study, we investigated the effect of the type of binder and mass fraction of the H 2 SO 4 solution used on the curing, soaking, and leaching behavior of agglomerations. The results revealed that Portland cement (3CaO·SiO 2, …
Properties governing the flow of solution through crushed ore …
Agglomeration with modified cement may provide a novel, cost-effective method for the treatment of low-permeability ores in acid medium (e.g. copper, uranium and nickel), since cement agglomeration has only been applied commercially in alkali medium (e.g. cyanide solutions for gold ores) to date. Desliming is less attractive due to the high ...
