Description
Opis patentowy opublikowano: 89 03 312 145 351 Regulowane chlodzenie grudek z wytrzymaniem izotermicznym polega na schladzaniu z dowolna predkoscia od tempetatury prazenia utleniajacego do zadanej temperatury z przedzialu od 950±50°C do 650±50°C, najkorzystniej do temperatury 750°C, wytrzymaniu przy tej tempera¬ turze w czasie nie krótszym niz 5 minut, najkorzystniej 25 minut z dalszym schladzaniem grudek w kapieli lugujacej lub na wolnym powietrzu do temperatury otoczenia.Regulowane ciagle chlodzenie grudek lub chlodzenie z wytrzymaniem izotermicznym umozli¬ wia wytworzenie faz krystalicznych w miejsce szkliwa i przez to stwarza mozliwosc lepszego wyodrebnienia i odprowadzenia wanadu do lugujacej kapieli niz w przypadku chloczenia niekon¬ trolowanego bezposredniego, przez co uzysk wanadu wzrasta od 50 do 100%.Przyklad I. Grydki wykonane z koncentratu tytanomagnetytowego zawierajacego 2,1% SiC2; 3,34% TiC2 i 0,43% V z dodatkiem weglanu sodu; po prazeniu utleniajacym w temperaturze 1350°C przez 60 minut schlodzono szybko do temperatury 900°C, dalej chlodzono wolno w zakresie temperatur 900-600°C w ciagu 15 minut, a nastepnie zanurzono w wodzie lugujacej i lugowano przez 20 godzin. Uzysk wanadu wyniósl 80%.Przykladu. Grudki jak w przykladzie I, po prazeniu utleniajacym w temperaturze 1350°C przez 60 minut schlodzono w ciagu 10 minut do temperatury 650°C, wytrzymywano w tej tempera¬ turze przez 25 minut, a nastepnie schlodzono do temperatury pokojowej w ciagu 15 minut. Uzysk wanadu po lugowaniu wyniósl 85%. PLThe patent description was published: 89 03 312 145 351 Controlled cooling of the pellets with isothermal resistance consists in cooling at any speed from the oxidative roasting temperature to the set temperature in the range from 950 ± 50 ° C to 650 ± 50 ° C, most preferably to the temperature of 750 ° C, withstanding this temperature for not less than 5 minutes, most preferably 25 minutes, with further cooling of the pellets in the leaching bath or in the open air to ambient temperature. The controlled continuous cooling of the pellets or cooling with isothermal strength allows the formation of crystalline phases in place of the enamel and thus offers the possibility of a better separation and drainage of vanadium into the leaching bath than in the case of direct uncontrolled dipping, whereby the vanadium yield increases from 50 to 100%. Example I. Buckles made of a titanomagnetite concentrate containing 2.1% SiC2; 3.34% TiC2 and 0.43% V with the addition of sodium carbonate; after oxidative calcination at 1350 ° C for 60 minutes it was cooled rapidly to 900 ° C, further cooled slowly at 900-600 ° C for 15 minutes, then immersed in leaching water and leached for 20 hours. The vanadium yield was 80%. The pellets as in Example 1, after oxidation calcination at 1350 ° C. for 60 minutes, were cooled in 10 minutes to 650 ° C., held at this temperature for 25 minutes, and then cooled to room temperature within 15 minutes. The vanadium yield after leaching was 85%. PL
