Goldmine effluents are often characteried by high concentrations of copper ammonia and cyanide derivatives mostly cyanates and thiocyanates. While not acutely toxic to birds this water can be acutely toxic to fishes and invertebrates. In many jurisdictions the effluent requires further treatment in order to pass a mandatory requirement to be nonlethal to species like the rainbow trout

THE SECONDARY PRECIPITATION OF GOLD IN ORE BODIES ALBERT D. BROKAW University of Chicago Secondary enrichment of ore deposits has been recognied as a subject of fundamental importance to the economic geologist and in recent years has received considerable study both in the field and in the laboratory
Mining effluents are promising for reuse but for this haardous metals and ions such as sulfate must be removed efficiently. This study aimed to compare the technicaleconomic performance of Nanofiltration NF and Direct Contact Membrane Distillation DCMD on gold mining effluent treatment
An ICPMS method for ultratrace AuPt and Pd determination in geochemical exploration samples is different effects on the condition of enriching and separating AuPt and Pd with Te as the coprecipitation were samples were
Mining produces mainly tailings the waste materials left after the valuable ore is separated out and overburden the waste materials removed to reach the ore. During the mining process water within and around the mine is usually contaminated so treating the mine water before it is discharged back into the environment is a major issue 2
Examine how the industrial byproducts from Canadian smelters contribute to the production of acid precipitation
201313Once the gold has been dissolved in the cyanide and the ore body has been reasonably depleted of its gold there are two main processes for recovering the gold from the pregnant cyanide solution. One is the MerrillCrowe inc precipitation process and the other is the adsorption of the gold onto activated carbon
The aim of this study was to evaluate an innovative treatment route for goldmining effluents rich in calcium arsenic and sulfate. This treatment route comprised two nanofiltration NF stages and a twostep intermediate precipitation
202031The bench scale test program also provided valuable data to advance the design of the mine water treatment plant from preliminary to detailed. McCue successfully utilied an unconventional chemical precipitation program to remove antimony chromium and copper
