| Abstract: | Briquetting is an age-old process for agglomeration of ore fines. It is mainly used for effective smelting-reduction, transportation, and storage purposes. The process is commercially in use for agglomeration of ore fines (Fe, Cr, Mn, etc.), fluxes (CaO, MgO, CaF2), sludges, slags, metal fines (Co, Ni, etc), coal, biowastes, and plastics. The fines of 0–6 mm sizes are converted into briquettes of 10–150 mm sizes using binder such as molasses, cement, resins, starch, tar, etc. using compaction pressure upto 150kN/cm. The preferred compressive strength of briquettes is between 50 and 250 kgf, and shatter index should be >90%. Roll and extrusion briquetting are the most common commercial technologies, which are supported by other subprocesses such as drying, mixing, and curing. The roll briquetting process has progressed by integration of high-power screw feeders, advanced hydraulic loading systems, and superior roll materials. The extrusion briquetting technology has also added advanced features such as stiff extrusion, versatile briquette dies and twin shaft extrusion to handle more moist and sticky materials. Briquetting is an inexpensive and versatile process with low operating cost which generally varies between $5/ton and $30/ton. High binder cost, difficult mixing of moist fines, and high maintenance cost due to abrasiveness of materials are the key technological challenges. The technology has potential to resolve various environmental issues by increasing recycling and reuse of process rejects, sludges, slags, and biowastes. This article summarizes process insights, product quality criteria, technological journey of compaction processes, process selection strategy, and potential of technology to shape future of mineral industry.
