To ensure optimal conditions for the microorganisms to act, the pH, temperature, and stirring speed were controlled. Finally, from the microbial action and using agricultural fertiliser (N:P:K sources), a copper extraction of more than 85% was achieved. 2012 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49623221016 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.172 Vol.79 |
