Hydrometallurgy an overview ScienceDirect Topics
In hydrometallurgy two types of oxides are important binary oxides which contain only one metal and complex oxides containing several metals Both types have mostly an ion structure and the metal atoms are characterised by high coordination numbers often 6 or 8 The most important structures of the binary oxides considered in hydrometallurgy are presented in Table 2 1
