Further on, nickel products can be divided into three groups: 1. Refined nickel (class I), nickel content 99 % or more. The group includes electrolytic nickel, pellets, briquettes, granules, rondelles and powders/ flakes. 2. Charge nickel (class II), nickel content less than 99 %. The group includes ferronickel, nickel oxide sinter and utility nickel. 3.
