“…Kurikka Calcite Marble Deposit A high-grade calcite deposit, which was mainly composed of calcite, silicates (quartz, tremolite, feldspars, diopside, mica, and serpentine), and graphite from sub-microscopic size to about 0.2-1.5 mm, and rarely, hydrated iron oxide and sulphides (Chernet et al 2006). The authors mentioned that the presence of fine-grained graphite in the deposit was responsible for the uneven grey colour of the calcite marble and it also lowers the deposits' grade as a source for GCC (Pekkala 1985).…”

In general, precipitated calcium carbonate (PCC) is used as a mineral filler in paper industries; while natural calcite (CaCO3) ore is also suitable for industrial use if it is a finely ground high-grade material. Naturally, calcite is found in the form of high- or low-grade ores and it is one of the most widely distributed industrial minerals on the earth’s crust. However, it is rarely found in its pure form and is generally associated with other gangue minerals; the type and percentage of which vary from one deposit to another. These minerals are generally separated by flotation and/or magnetic separation (in the case of iron impurities). Calcite ores typically contain metal sulphide, silicate, or other calcium-containing impurity minerals, which can be removed by flotation. A tremendous amount of research has been performed on refining the flotation process for calcite ores and designing the reagents (specifically, collectors) to increase the efficiency of the process. Metal sulphide/silicate impurity minerals can be removed by the froth-flotation process using amines and xanthate collectors. Alternatively, fatty acids are used as collectors to float calcium-type minerals directly from the ore. This paper reviews the industrial practices and fundamental research related to collectors surrounding calcite ore flotation. This article presents and reviews collectors for the beneficiation of high-grade calcite ores which have been reported in the literature in order to assist judicial choice of collecting agents in flotation.

Extracciones de cobre.Metallurgical behavior of fine fractions of copper sulfide minerals in a combined process of modified flotation and agitated bioleaching AbstractThe metallurgical behavior of fine fractions of copper sulfide minerals of Compañía Minera Quebrada Blanca S.A. was studied by concentration through flotation in aqueous media modified by alcohol followed by bioleaching of the concentrates. By using a 1 % v/v of methanol, the metallurgical recovery of copper reaches 88 %, while the iron recovery was 43 %, the weight recovery was 18%, which indicates a high selectivity. These concentrates were then bioleached with and without nutrient medium, reaching 80 % of copper recovery after 10 and 17 days, respectively. Then, it is possible to conclude that this concentration-bioleaching metallurgical process is a promising route for copper recovery from the fine fraction of sulfide minerals.
