Container with ash is placed in flow cabinet, and 3 kg is taken out to a plastic bucket. 2. The ash is transferred to the reactor via a funnel (Alternatively: 2. The ash is mixed with water in the bucket and the slurry is transferred to the reactor via a funnel) 3. The reactor is loaded using a liquid transfer pump (peristaltic pump) with water and 50% sodium hydroxide up to 18L 4. The mixture is stirred and heated to 80°C 5. The reactor content is pumped out of the reactor (using a liquid transfer pump) into a 20-L filter unit; the filter cake is washed with demi water via the pump. 6a. The filter cake is collected in a plastic bucket with lid and will not be processed further in the demo 6b. The hot filtrate is transferred to another reactor using a liquid transfer pump. It is then stirred and cooled. 8. The reactor content is pumped out of the reactor (using a liquid transfer pump) into a 20-L filter unit; the filter cake is washed with 1.8L demi water via the pump. 9a. The filtrate is transferred to a 20-L jerry can and will be processed later in the demo. 9b. The moist cake is taken out of the filter and transferred to a reactor; the reactor is loaded further using a liquid transfer pump with water and 50% sodium hydroxide up to 18L. 10. The reactor is stirred and heated till all crystals are dissolved; then the reactor content is cooled to provoke crystallization. 11. The reactor content is pumped out of the reactor (using a liquid transfer pump) into a 20-L filter unit; the filter cake is demi washed with 1.8L water via the pump. 12. Steps 9-11 will be repeated in some demo runs 13. The moist cake is taken out of the filter, and transferred to a reactor; the reactor is loaded further using a liquid transfer pump with water up to 17L. 14. The mixture is stirred, and 50% sulfuric acid is added to the mixture via a liquid transfer pump. 15. Aluminum sulfate solution is added, and the mixture is heated to 80°C and stirred . 16. The reactor content is pumped out of the reactor (using a liquid transfer pump) into a 20-L filter unit; the filter cake is demi washed with 1.8L water via the pump. 17A. The moist filter cake is collected in a plastic bucket with lid and will not be processed further in the demo 17B. The filtrate is transferred to a reactor and 50% sulfuric acid is added and the mixture is heated to 80°C and stirred.. 18. The reactor content is pumped out of the reactor (using a liquid transfer pump) into a 20-L filter unit; the cake is washed with 1.8L demi water via the pump. 19A. The filtrate is transferred to a 20-L jerry can and maybeprocessed later in this demo 19B. The moist cake is taken out of the filter, and transferred to a reactor; the reactor is loaded further using a liquid transfer pump with water up to 17L. 20. Sodium hydroxide solution is slowly added to the mixture until most of the material is dissolved.. 21. The reactor content is cooled to 5°C, and the reactor content is pumped out of the reactor (using a liquid transfer pump) into a 20-L filter unit. 22A. The residue on the filter is collected in a plastic bucket with lid and will be not processed further in this demo 22B. The filtrate is pumped slowly over an ion exchange column.. 23A. The outflow of the column is collected in 2 20-L jerrycans 23B. The column is regenerated by rinsing with 2.5 M sulfuric acid 23C. The washing liquid is collected in 20-L jerrycans; in some runs it may be used to replace sulfuric acid in step 14 and 17b. 24. Column outflow solution (partial) is transferred into a reactor and sulfuric acid solution is added till a clear yellow solution is obtained and the solution is transferred to a 20-L jerrycan. 25. The yellow solution is fed to the electroreduction cell to be converted into vanadium (IV) sulfate solution, which is stored in a 20-L jerrycan 26. Column outflow from step 23A is fed to a reactor using a liquid transfer pump and vanadium (IV) sulfate solution is added us ## Relevante data voor Phoenix Metals [Wordt ingevuld na kruisanalyse] ## Key artikelen / paragrafen ## Kruisverwijzingen [Wordt ingevuld na kruisanalyse]
