Abstract

Keksintö koskee menetelmää nikkelirikasteen valmistamiseksi magneettikiisu-pentlandiitti-malmista. Menetelmässä malmi hienonnetaan siihen maksimiraekokoon, jossa pääosa sulfidimineraaleista vapautuu silikaatti- ja muista harmemineraaleista ja vapautuneet arvosulfidit ovat suoraan tai lisähienonnuksen kautta rikastettavissa korkealaatuisiksi lopputuotteiksi, hienonnetusta malmista erotetaan magneettisesti magneettikiisua sisältävät partikkelit magneettiseksi rikasteeksi (M1). Magneettisen erotuksen jätteenä saadut epämagneettiset tuotteet (EM1, EM2) toimitetaan vaahdotukseen, jossa tuotetaan nikkeli- ja/tai muut arvosulfidirikasteet.The invention relates to a method for producing nickel concentrate from pyrite-pentlandite ore. In the method, the ore is crushed to the maximum grain size at which the majority of the sulfide minerals are released from silicate and other impurities and the released valuable sulfides can be enriched directly or through additional crushing into high-quality end products, particles containing pyrite are magnetically separated from the crushed ore into a magnetic concentrate (M1). The non-magnetic products (EM1, EM2) obtained as waste from the magnetic separation are delivered to flotation, where nickel and/or other valuable sulfide concentrates are produced.
