The Objective of the Study is to characterize the process of heap leaching of the technogenic mineral granules obtained from different types of mining waste (cut-off grade ore, mature tailings, and tailings of the current ore processing) by a reagent complex containing sodium cyanide solution and hydrogen peroxide to enhance the gold recovery …

The current paper presents research aimed at replacing in flotation of copper pyrite ore, bearing gold and silver, the classical depressor lime with catholyte, i. e. with solution obtained during ...

A sulfidization roasting-flotation process was usually viewed to be effective in treating the refractory oxide ore. In this paper, pyrite was proposed to be applied as a potential vulcanizing reagent to transform PbO or its surface to PbS based on feasibilities of technology and economy. The evolution process, phase and characteristics of crystal …

Materials and reagents. The Nussir ore material was handpicked from two different parts of the mine, Nussir North East (P1) and Nussir Old West (P2). Crushing and milling of these samples was performed in a jaw crusher with a 3 mm opening and sieved to the −150-µm size fraction. ... The flotation separation of sphalerite from pyrite through ...

To investigate whether pyrite affects the adsorption of Zn precipitates on sphalerite, the contact angles of sphalerite in the absence and presence of pyrite were measured using a small cuboid crystal of sphalerite and pyrite under the same conditions as the flotation experiments; 50 ppm zinc sulfate, 5 ppm PIPX, and 20 μL/L MIBC at pH 9 and ...

Multiplying the ratio set point with the incoming ore flow yields the amount of reagent needed to achieve the required pH level. ... Nevertheless, in porphyry copper mines lime is the preferred reagent for pyrite depression, and, more generally, for pH control. This implies high reagent consumption and has other processing consequences.

Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.

Pyrite Ore. 1000. Pyrite Ore. Crafting Reagent. Sell Price: 10. Pyrite Deposit. Pyrite Ore is a metal ore found only in Cataclysm zones. A minimum mining skill of 525 is needed.

The depression of sulphide minerals by sulfoxy reagents has been widely studied and a number of mechanisms have been proposed. Sulfoxy species are supposed to depress pyrite by forming metal sulphite precipitates, promoting the oxidation of pyrite to form copper/iron hydroxides/sulphates or decomposing hydrophobic sulphur species to …

Even if more selective separation was achieved from the pyrite flotation (selectivity index∼5), 40% of sphalerite in the ore was transferred into the pyrite concentrate. In addition, the results of the collectorless tests indicated that more than 80% of the gold can be recovered, and higher selectivity indexes (up to 10) are achievable.

Introduction. Pyrite (FeS 2, iron disulfide), is the most abundant sulfide mineral and commonly associated with valuable minerals such as sphalerite, chalcopyrite, galena, gold as well as coal (Wang and Forssberg, 1991, Wang, 1995, Dimitrijevic et al., 1996, Jiang et al., 1998).Pyrite has very low economic significance and is usually …

The RGO and pyrite used in this study were obtained from a gold smeltery in Hunan Province, China. The RGO and pyrite were dried in a vacuum at 60°C for 12 h, ground, and then sieved to obtain particle sizes below 200 mesh. Analyt-ical-reagent grade thiourea was kindly provided by Sino-

The largest gold ore object in Kazakhstan is the Vasilkovskoye deposit, 17 km northwest of the city of Kokshetau. The Vasilkovskoye deposit belongs to the gold-quartz moderately sulfide formation. The main ore minerals of primary ores are arsenopyrite, pyrite, bismuth minerals and native gold. Arsenopyrite sharply …

To verify the impact of Fenton reagents on the performances of flotation separation, micro-flotation experiments were performed on the artificial mixed ore of pyrite and chalcopyrite. The findings, as shown in Table 1, the Fenton reagent has favorable in separating the artificially mixed pyrite and chalcopyrite ore. Specifically, the ...

All of them promoted the electron transfer from anionic reagent to mineral surface. For pyrite, as impurity is beneficial to the adsorption of O 2, whereas for the pyrite containing Co and Ni impurities, ... In addition, studies on coal/ore pyrite depressants and their mechanisms, flotation characteristics of depressants, and reagent/mineral ...

This manuscript discusses the main chemical and physical mechanisms involved in the phenomena of reagent adsorption on the mineral surface, the impact of pH and type of alkalizing agent, and the effect of pyrite depressants, some already …

In real ore systems, many ionic species can modify the surface properties of pyrite and change its flotation behavior. Download ... Since dixanthogen is the main species responsible for pyrite flotation, any reagents that are more reducing than the X-/X 2 couple are supposed to act as pyrite depressants by preventing oxidation of xanthate ...

In laboratory experiments, this new reagent system achieved a substantially better separation of copper-gold sulfide ore and pyrite than the conventional process …

Fourteen reagents that are potentially capable of chelating with a metal ion on the surface of the major copper sulfide minerals and pyrite were evaluated for their effectiveness in floating these sulfides. The reagents studied fall into the classes of mercaptobenzole mutations, thiouronium, thionocarbamates, thiourea, imidazole …

Abstract. As high-grade ore deposits become depleted, there is an increasing demand to process marginal low-grade ores with complex metallurgical challenges. …

Materials and reagents. The pyrite was obtained from Yunfu, Guangdong Province, China, and the talc was obtained from Haicheng, Liaoning Province China. ... The flotation time was 3 min, the amount of artificial mixed ore was 2 g, and the ratio of pyrite to talc was 1 : 1. PAX was used as the collector, and guar gum was used as the inhibitor.

This ore has primarily free gold species, a very small amount of gold associated with pyrite, and 5.6% by weight of the ore is pyrite. The trends shown in this figure are very typical of a large number of plant ores that this author has worked with. ... Whenever possible, to reduce reagent and capital costs and to get the highest possible …

Therefore, using available, affordable, eco-friendly polymers to assist or replace hazardous reagents is mandatory for a green transition. Polysaccharide-based (starch, dextrin, carboxymethyl cellulose, guar gum, etc.) polymers are one of the most used biodegradable depressant groups for pyrite depression.

Here, based on the commonly used pyrite depressants, recent studies on the surface properties of sulfide minerals, flotation characteristics of reagents, and …
