Abstract

Изобретението се отнася до извличане на никел, кобалт и на метали от подгрупата на платината и паладия чрез растения от рода Brassicaceae, по-специално Alyssum видове, отглеждани в почва, съдържаща посочените метали. В почвата се създават подходящи условия чрез поддържане на ниска стойност на рН, ниска концентрация на калций и чрез добавяне на амониеви торове и хелатни агенти към нея. Акумулирането на никел е около 2,5% и повече в надземните растителни тъкани, с което се създава възможност за извличане на метала чрез обработката на растителнияматериал, който се изсушава и изгаря, за да се окислят и изпарят органичните материали и да се извлече натрупаният в тях метал, в концентрация 10-20 пъти по-висока от тази в почвата, при това във вид, който може да бъде използван при конвенционалното рафиниране или топене на никел.
