Chemical compounds that adhere to the surface of the mineral particle, allowing them to float and levitate together with air bubbles. This process occurs in a floating cell.

• Isopropyl Sodium Xantate
• Isobuthyl Sodium Xantate
• Amil Potassium Xantate
• Modified Tionocarbamate
• Aril and Alquilo Sodium Ditiofosfatos
• Isopropil Ethyl Xantoformate

Surfactants that reduce the water surface tension in order to produce a semistable foam, that holds the floating mineral particles, until they can be physically removed from the floating cell surface.

Compounds that reject the flotation of unwanted minerals.

Chemical compounds that condition the PH in order to allow an efficient flotation.

Hydrophobic oximes that extract, in a selective way, the cupric ion through solvents coming from the liching process, giving place to concentrated copper solutions, which are subsequently treated in electrowining plants. (EW).

Mixtures of paraffin aromatic hydrocarbons, properly dosed. They are used as diluents for the extraction processes through solvents, according to the characteristics of extractants and ores.

Salt that acts as catalyst in the copper deposit process through electrochemical reduction.
