Silver ore minerals. Silver ore minerals refer to the naturally occurring compounds or elements that contain silver as a major component and are typically found in silver ore deposits. Some of the common silver ore minerals include: Argentite (Ag2S): Argentite is one of the most common silver minerals and is a silver sulfide.It is typically found in hydrothermal vein deposits …
Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with changes arising in the …
This study presents a predictive geometallurgical model for the Ouansimi copper deposit in Morocco, focusing on the flotation of mixed copper ores. The deposit was divided into two geometallurgical domains (GMD) with distinct oxidation rates using K-means clustering. The principal component analysis-partial least squares regression method was applied to establish …

Optimal flotation conditions were determined to be pH 6, a pH conditioning time of 7 min, and dosages of 50 g/t, 100 g/t, and 20 g/t of sodium hexametaphosphate, X-231, and DF250, …
The first step is bulk copper-cobalt flotation, followed in a second step in which the flotation of the cobalt minerals is suppressed. Perfect separation of copper and cobalt by flotation is not possible: typical assays of the cobalt content of the copper-rich concentrate range between 0.5 and 0.25% (with copper assays between 28 and 32% ...

The copper-cobalt-silver mineral deposits are composed of sediment-hosted fine-grained sulphides. Copper is primarily hosted in chalcopyrite, with accessory chalcocite and bornite, with Cobalt is primarily in the form of carrolite. ... Following flotation concentration, mineralisation from Emmie Bluff and Windabout will be fed through the ...
Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment of copper oxide ...
Aromatic dithiophosphates are used preferentially for the flotation of lead minerals, often containing silver. - Thiocarbamates are a family of organosulfur collectors. ...

Flotation may also prove to be the more economical process for an ore containing such minerals as stibnite, copper-bearing sulphides, tellurides, etc., which require roasting before cyanidation, since it reduces the tonnage passing through the furnace to a fraction of the original feed with considerable reduction of working costs in consequence.
There are many minerals in nature that contain cobalt, and it is typically obtained as a by-product from copper, nickel, silver, gold, lead, zinc, manganese, arsenic, and iron ores [7, 8]. Therefore, the mineral enrichment pro-cess is planned according to other minerals []. Cobalt 9 mineralization is typically found in the form of Cu-Co
