energy audit guideline for gold tailings recovery process unit

  • Energy Efficiency in the Chemical and Refining Industries

    The acid recovery process is energy intensive and uses largevolume hightemperature furnaces that are fired with natural gas. The spent acid must be injected into the furnaces and decomposed to permit recovery of the sulfurcontaining portions of the waste stream. As shown in Figure 1 the plant has implemented a number of improvements to reduce energy consumption in these furnaces.

  • AN AUDIT OF COMPLIANCE AND ENFORCEMENT OF THE MINING

    During the course of this audit these risks became a reality and disaster occurred when the tailings dam at Mount Polley failed releasing approximately 25 million cubic metres of wastewater and tailings into adjacent water systems and lakes. It may be many years before the financial environmental and social implications are fully known.
