Effect of the particle size and microstructure characteristics of
2021.3.1 Although the heap leaching is widely used in industry, the process is still limited by low recovery rate and long extraction time (Ghorbani et al., 2011; Ghorbani et al., 2013a; Lewandowski, 2008). The low extraction efficiency is explained by the fact that liquid channeling or leachate is extremely difficult to penetrate large-sized ore (Ghorbani et al.,

Control of Zinc-containing Dust Agglomerates in Basic Oxygen
to form agglomerates and the equipment is easy to clean, therefore, there is no zinc-containing dust agglomerates in the electric furnace dust cleaning system. If zinc concentration is controlled in basic oxygen fur-naces as in blast furnaces, it will inevitably affect the uti-lization of galvanized steel scrap as an excellent recycling resource.

Current situation of carbon emissions and countermeasures in
Recently, a new charge of iron–carbon agglomerates (ICA) has also been proposed, which is prepared by mixing iron ore and coal. It has the advantage of high reactivity un-der the catalysis of metallic iron. The preparation of this new charge usually uses the conventional chamber coke oven method and the briquette shaker method [23]. The new bur-
