Control Room TrainerFull Time

• Job Details:My position involves working as part of a team operating the control room using SCADA Wincc System with the following key responsibilities; Significant use of spread sheets, word documents and databases. Produce daily management reports. Use asset management software to analyze system component efficiencies, maintenance and costs. Work closely with, civil crews, mechanical crews, electrical crews, management and the engineering department. Incident management - Direct incidents, produce incident logs and produce management and environmental authority reports. Responsible for optimization of process flow. Have input to production planning – optimizing plant. Operate process plant as efficiently and safely as possible, to maintain quality of products required in area of responsibility. Monitor and control all plant and equipment within designated area and respond to conditions accordingly. Ensure production targets for units are met. Ensure operational and maintenance requirements are carried out with the co-operation of the outside operation staff. Start up and shutdown units in a safe manner and in accordance with procedures. Crushing circuit Responsible for operation of primary and secondary crusher with a set point of required tonnage. Make a pre-start at beginning of the shift which includes checking of mantle position and making a gap test to maintain the outlet material at a required size to keep tonnage at set point. Check all lubrication systems in both crushers and also check the level of oil lubrication tank at safety level and make sure that all lubrication pumps run at normal conditions like suitable speed and current. Check all conveyers healthy and ready to go, also check all interlocks like belt rip, belt drift, pull safety wire, tail and head pulley drums free of blocks. Grinding circuit Responsible for operation of mills at a set point of required tonnage. Check the lubrication system in each mill; also make sure all lube pumps running at normal speed and current to keep the flow rate of the oil at a suitable range. Check the power and current of each mill according to set point of each mill to keep all motors at safety mode. Check all mills discharge pumps running at normal speed and current in programmed mode according to set point of mills discharge hopper levels and cyclones pressure, etc… Check all conveyers running at healthy mode and free of any interlocks. Make all start-up and shutdown procedures of all circuits. Flotation circuit Check all flotation rougher cells running with addition of suitable amount of blowered air to each cell with help of controlling the frother depth of each cell through open or close percentage of pinch sleeve valves at the bottom of each cell. Control amount of air added to each cell through control box which connects between set point of air addition and actual opened percentage of pneumatic air valve. Control all chemical reagents addition to the flotation circuit at a suitable range according to the actual tonnage to ensure high recovery of gold. Check flotation cells underflow and overflow pumps running at normal speed and current. Thickening circuit Check all thickeners running at normal conditions like rake drive working at suitable torque according to bed mass set point. Make sure those thickeners running with help of suitable addition of flocculating agents to get all bed levels down so as we get high recovery of clear water overflowing thickeners which used again as a process water. Control the underflow density by controlling the speed of thickeners underflow pumps according to set point of required flow rate. Carbon In Leach Tank circuit Check all intertank screens running in normal current and speed. Control all densities in all tanks by adding or reducing water addition in each tank to keep amount of carbon used at the required range. Ensure that we get high recovery of gold in this circuit by addition of controlled amount of cyanide solution according to the required set point of CN Concentration in ppm with help of lime addition to keep the slurry at a suitable range of PH. Ensure that air lifting system is working in right way to keep oxygen amount in each tank at required range which is important for leaching process on carbon particles surfaces which transferred in a counter-current flow. Gold Recovery Circuit Perform loaded carbon transfer from CIL circuit to the acid washing tank where the loaded carbon is washed by addition of HCL solution and fresh water to clean the carbon from all impurities. Perform elution process in the elution tank where chemicals added in suitable amounts like caustic cyanide and caustic soda to extract gold from carbon to obtain a concentrated solution of gold. Perform electrowinning process which is the last phase of recovery of gold. Ensure that the current and voltage of electrowinning cells at suitable range required for electrolysis.
