It involves heating the fine ores at high temperatures, where simultaneous oxidation & agglomeration of the ores take place. For example: lead sulfide(PbS) ores are subjected to sinter roasting in a continuous process after froth floatation to convert the fine ores to workable agglomerates for further smelting operations.

Agglomeration drums, also called ore drums, agglomerators, and heap leaching drums, are based on a rotary drum design: a large, rotating drum tumbles material through its interior to accomplish the process goal. In the case of the heap leaching process, ore fines are tumbled through the drum prior to heaping on the leach pad.

Before leaching, raw low-grade copper ores are typically crushed using high-pressure grinding rolls to induce the formation of numerous microcracks and fine mineral particles (Yin et al., 2017); this step can accelerate the leaching process and increase the leaching recovery, but it reduces the penetration of the leachate into the ore.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
