1.2.3 Retort The retort system is designed to treat spent activated carbon and filter cake from the calomel treatment caustic leach circuit discussed in Section 1.2.2 above. The retort system and its location in the Process Area are shown below (Figure 1.2-4). Figure 1.2-4: Retort and Location in Process Area PMR RCRA Permit Application, Dry Hills Facility Page 24 JBR Environmental Consultants, Inc. | HATCH March 2013
Activated carbon is used in the air emission control equipment (e.g., carbon beds) at BGMI, as well as other Barrick facilities. Spent activated carbon, a mercury-bearing material, will be shipped to the proposed TSF in 55-gallon steel drums. The drums will be off-loaded from trucks to temporary storage per procedures outlined in Section 1.2.1. The retort system for the proposed TSF will be designed to accept feed materials in both 55-gallon drums and vendor supplied retort trays. The spent activated carbon drums will be transferred to the retort for processing. The design retort capacity is two 55-gallon drums of spent activated carbon per batch. Once a batch of spent activated carbon or filter cake is placed on the retort stand and the retort dome is set, the operator will initiate a pre-determined retort temperature and pressure cycle, consisting of the following steps: 1. A vacuum will be developed in the sealed retort, which promotes evaporation of volatile components (e.g., water, mercury, etc.) from the feed. 2. The retort temperature will be increased and maintained at a lower temperature sufficient to remove moisture from the feed. 3. The retort will be heated to the upper operating temperature to evaporate/sublimate mercury compounds and will be maintained at an elevated temperature for a fixed period of time. Near the end of the heat cycle, small amounts of bleed air will be added to the retort to promote deportment of mercury vapor to the retort off-gas system. 4. After the heating step is complete, the sealed retort will be left to cool. Cooling air will be drawn into the retort to promote cooling of the retort shell. The spent activated carbon and filter cake will be processed in separate batches and will not be mixed as the retort temperature and pressure cycles will be customized to suit the specific feed material. After the retort cycle is complete, the drums or retort trays will be unloaded from the retort stand. The retorted carbon as well as the drums will be tested using EPA methods to determine the hazardous characteristics and evaluate Land Disposal Restrictions (LDR) standards as described in Appendix 2-A. Residues that are determined to be hazardous by characteristics (e.g., do not pass the TCLP test) or do not meet LDR standards, may be reprocessed or shipped to an appropriately licensed facility for further treatment and disposal. Other materials will be managed as appropriate (e.g., recovery of precious metals, off-site disposal, etc.). Similarly, the retorted filter cake residue will be tested to determine the hazardous characteristics and appropriate management. In order for the proposed TSF to reach its maximum throughput of treating 240,000 pounds of spent activated carbon and 612,000 pounds of calomel per year, two identical retorts will be required. See H340940-0000-50-042-0002 in Appendix 1-A for a general arrangement of the process area.
