Whereas, direct furnacing has been regarded as the standard process for mercury (cinnabar) ores, hydrometallurgical methods offer an alternate consideration. The chemistry of this process is not new, but with the
Leaching Plant Design
Table of ContentsModern Leaching Plant DesignImportance of Laboratory Testing to Leaching Plant Design Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design

Segregation Process of Mixed Sulphide Copper Ore
Table of ContentsThe FlowsheetCRUSHING AND SCREENINGSEGREGATION TREATMENTGRINDING AND CLASSIFICATIONFLOTATIONCONCENTRATE DEWATERING Sulphide copper ores are normally concentrated by flotation while the oxide ores undergo hydrometallurgical treatments. The mixed sulphide-oxide copper ores may be processed by combined methods such as flotation followed by leaching and precipitation of the oxidized portion, or vice-versa. Also a Leach-Precipitation-Float Process (LPF Process) has been successfully applied.

Effect of NaCN Cyanide Dosage on Depression of Sulphide Minerals VS pH
At the dosage of collector (not shown but relatively low), it is indicating galena will not float above pH 10.4, and it is not affected by NaCN. What you have to be careful about is that these lines all move if you increase or decrease the collector dosage. For example, you can get pyrite to float above pH 9 if
