Abstract: The present invention refers to a method to remove organic chemicals and organometallic complexes (organic heavy metal complexes) using zeolite from process water or tailings streams of a mineral processing plant where diethylenetriamine (DETA) or triethylenetetramine (TETA) is used as a flotation reagent and DETA-metal complexes are found in process water or tailings streams. In a preferred embodiment, the process water or slurry tailings streams of a mineral processing plant containing DETA, DETA-metal complexes and residual heavy metals are contacted with natural zeolite. This can be carried out by adding the natural zeolite to the process streams (slurries) while mixing with a mechanical mixer to efficiently adsorb DETA, DETA-metal complexes and heavy metals from the process streams (slurries) on the zeolite. The loaded zeolite is then discarded with the flotation tailings.

Abstract: A water or wastewater treatment method includes the steps of providing an Fe source, the Fe source including an Fe salt or relatively high surface area Fe metal arrangement, such as a volume of Fe filings, steel wool, or Fe nanoparticles. The Fe source is contacted with influent water including at least one contaminant or chelating agent bound contaminant in the presence of an oxygen comprising gas flow, such as air. The outlet flow following the contacting step provides a reduction in a concentration of the contaminant and/or chelating agent from its level in the influent through oxidation of the contaminant or precipitation, co-precipitation, or reduction to metal form of the contaminant with the Fe source to form a metal sludge. The method can include a separating step including sedimentation or filtration of the transition metal sludge from the outlet flow.
