The history of mineral processing is as old as that of a man. Cleaving stones, sharpening flint stones and sorting were one of the first mineral processing activities practiced by humans. A considerable development of mineral processing and its phys-icochemical basis took place within the last hundred years. Processing of useful min-

The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed …

Abstract. The aim of this paper is to reflect on efforts made worldwide to construct processing centres where artisanal miners can visit to have gold extracted from ore "free" or for a nominal fee. These centres use inefficient grinding and amalgamation processes to extract less than 30% of the gold to give back to the miners.

The most mobile mineral ions during seed sprouting are those of K, Ca, and Zn, while Mn and Fe ions are less mobile (L. Lu et al., 2013). Lemmens et al. ( 2018 ) found that Zn was also detected in the pericarp tissues after sprouting, but it especially accumulates in the developing coleoptile and radicle, suggesting that Zn ions play a key role ...
