When prices improved, another new concentrator was constructed in 1895. It was unsuccessful at treating sulfide ores.

For many years as an integrated mine-concentrator-smelter operation, Morenci pioneered the large-scale hydrometallurgical treatment of mined copper ore by dump leaching, solvent extraction (SX) and electrowinning (EW) during 1985, in parallel with conventional treatment.

This occurs at a mill facility, which is known as a concentrator. The ore from the mine (averages 0.25% to 0.50% copper) is initially reduced in size to about 10 to 0.5-inches by a one or more stages of crushing. The crushed ore reports to a grinding circuit, where steel balls are used to further reduce it to a consistency of a fine beach sand.
