2018-1-1 A graph of mass of the ore used in the extraction against mass of the precipitate produced. The results show that the amines and uric acids in chicken waste can complex copper ions from ores just like the acid leached solution. Therefore the copper ions obtained from 6.0 g of the ore were later reduced by hydrazones species prepared in situ.

2019-11-1 Valero et al. proposed a general equation for estimating the energy consumption according to the ore grade: (1) E X m = A ⋅ X m − 0. 5, where E X m is the energy for the concentration and extraction of minerals at the ore grade (x m), and the coefficient A is determined for each mineral. In the methodology of Valero et al., the ERC of each element is calculated under the assumption that the
