“…One possibility would be their incorporation to secondary phases. Copper association with iron oxides or oxy-hydroxy-sulfates has been reported in earlier studies (Dutrizac, 1984;McGregor et al, 1998) and can be deduced in the light of the sequential extraction results from the column experiments (Fig. 7).…”

“…Diamagnetic dilution studies can also be made in which a non-magnetic ion, such as Al 3+ , Ga 3+ , or In 3+ , is substituted onto the B site. 16,11 In addition to this versitility in engineering various kagomé systems, control can also be exercised over the details of the interplane magnetic exchange by replacement of the SO …”

The jarosites make up the most studied family of kagomé antiferromagnets. The flexibility of the structure to substitution of the A and B ions allows a wide range of compositions to be synthesised with the general formula AB3 (SO4) (SO4) 2− groups by (SeO4) 2− or (CrO4) 2− . Thus, a variety of S = 5/2, 3/2, and 1 systems can be engineered to allow study of the effects of frustration in both the classical and more quantum limits. Within this family both conventional long-ranged magnetic order and more exotic unconventional orderings have been found. This article reviews the different types of magnetic orderings that occur and examines some of the parameters that are their cause.

“…Jarosite type minerals can be problematic in the bioleaching of chalcopyrite (CuFeS 2 ), contributing to passivation of the leaching as they precipitate on chalcopyrite surfaces as secondary solid phase oxidation products [23,24]. Jarosite precipitation is also extensively used in the zinc industry to remove Fe and other impurities from metallurgical circuits [14,15,25]. As opposed to removing iron as hematite (α-Fe 2 O 3 ) or goethite (α-FeOOH), the advantage of jarosite precipitation in the zinc industry is that there is less need for neutralization, and the precipitates settle and filter well with little loss of divalent metal ions (e.g., Ni, Cu, and Zn) in the washed residues [15].…”
