A new process for one-step extraction of antimony in low We describe the use of sulfiding agents to achieve a significant increase in the level of metal recovery during the smelting of copper concentrates and matte conversion. In the conversion process for copper and polymetallic mattes, the addition of sulfides produces (1) a remarkably low level of nonferrous metals remaining in converter Metal Recovery from Converter Slags Using a Sulfiding Agent

Minerals Free Full-Text Preparation of Antimony Sulfide and
Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were analyzed The positive correlation of antimony with silver, bismuth, and arsenic in these objects suggests that the metal was derived from fahlerz type copper ores rather than a mixture of pure copper and antimony–arsenic rich mineral [13: fig. 3.1].Why did the use of antimony-bearing alloys in Bronze Age

Minerals Free Full-Text Accessing Metals from Low-Grade Ores
Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in Xueyi Guo. Dong Li. Tungsten residue is a vital scandium-containing resource. This paper presents techniques to extract scandium from high-silicon scandium-rich tungsten residue by sulfuric acidXueyi Guo's research works Central South University, Changsha

New method developed for producing some metals MIT News
Credits. Courtesy of the researchers. The MIT researchers were trying to develop a new battery, but it didn’t work out that way. Instead, thanks to an unexpected finding in their lab tests, what they discovered was a whole new way of producing the metal antimony — and potentially a new way of smelting other metals, as well.Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide.

Antimony Recovery from End-of-Life Products and Industrial
These observations have led the European Commission to highlight antimony as a critical raw material in 2014, with an expected supply–demand gap exceeding 10 % over the period 2015–2020, which is the highest amongst all critical metals [].The processing of antimony ores and the production of antimony metal is also Why, it's simple: you heat a metal oxide with carbon, and you get the metal you were after, plus a byproduct of $\ce{CO}$ or $\ce{CO2}$ which easily flies away. Coal is still abundant on our planet. Try to pull that with a sulfide! I guess the reaction will not go in the first place, since $\ce{CS2}$ is a great deal less exothermic (*) thaninorganic chemistry Why are the sulfide ores generally converted

A novel approach to synthesizing sodium antimonate and
Arsenic–enriched wastewater (A–EW) is a hypertoxic sewage from the utilization of crude antimony oxides in lead anode slime metallurgy. In traditional methods, the H + accumulation inhibits the arsenic immobilization during scorodite synthesis. In this study, a novel multivalent iron source comprised of Fe(OH) 3 and FeSO 4 7H 2 O was various converting technologies applied in the copper production. The temperature in the converting furnace reaches 1100 C. 2.1.2 Secondary copper production A secondary copper smelter is defined as any plant or factory in which copper-bearing scrap or copper-bearing materials, other than copper-bearing concentrates (ores) derived from a miningEMEP/EEA air pollutant emission inventory guidebook 2019

Antimony (Sb) is a naturally occurring metalloid element. It can exist in a variety of oxidation states (−III, 0, III, V), but is mainly found in two oxidation states (III and V) in environmental, biological and geochemical samples [].The abundance of Sb in the Earth’s crust is in the order of 0.2–0.3 mg kg −1 [].The concentration of Sb in soils is higher than
