“METHOD FOR THE REMOVAL OF ORGANIC CHEMICAL PRODUCTS AND ORGANOMETALLIC COMPLEXES FROM PROCESS WATER OR OTHER CURRENTS OF A MINERALS PROCESSING PLANT USING ZEOLITE |
| abstract |
The present invention relates to a method for removing organic chemicals and organometallic complexes (heavy metal organic complexes) using process water zeolite or tailings streams from a mineral processing plant in which diethylenetriamine (DETA) is used or triethylenetetramine (TETA) as a flotation reagent and DETA-metal complexes are found in the process water or tailings streams. In a preferred embodiment, the process water or sludge tailings streams of a mineral processing plant containing DETA, DETA-metal complexes and residual heavy metals are contacted with natural zeolite. This can be done by adding the natural zeolite to the process streams (sludge) while mixing with a mechanical mixer to effectively adsorb DETA, DETA-metal complexes and heavy metals from the process streams (sludge) onto the zeolite. The charged zeolite is then discarded with flotation tailings. ) on the zeolite. The charged zeolite is then discarded with flotation tailings. |
