The effect of seawater ions and their aqua-complexes can impact positively and negatively depending on the mineral studied, operational conditions, and objectives searched. For example, the presence of copper ions can activate sphalerite and pyrite (Mu and Peng, 2019; Wang et al., 2019). Positive, negative, and uncharged copper

The ore body is a complex copper-gold porphyry deposit, comprising intermixed oxidized, transition and sulphidic gold and copper-bearing ores. Gold in the sulphide ores is generally not refractory and is recoverable by cyanide leaching, but the secondary copper minerals, which are also cyanide soluble, lead to high cyanide consumptions.
