Removal of Arsenic from Crude Tin by Vacuum Distillation

Arsenic is widely present in the process of ore-dressing, tailings recovery and smelting, which is poisonous and harmful. Current tech-nologies which can treat tin ore or crude tin have not achieved satisfactory economic and environmental effects. In particular, the existing pro-cesses have poor effects on arsenic removal from raw materials.

Comprehensive recovery of tin, sulfur and arsenic from

Comprehensive recovery of tin, sulfur and arsenic from the mixed mineral was studied. A joint flowsheet of flotation and gravity was developed according to the mineralogical characteristics of the sample. Flotation was carried out first to produce sulfur concentrate while the tailing was processed by a second flotation to obtain rougher arsenic

Arsenic Removal and Recovery from Copper Smelting

Removal and recovery of high levels of arsenic (As) in copper smelting wastewater present a great environmental challenge. A novel approach was investigated for the first time using TiO 2 for As adsorptive removal from wastewater and subsequent spent adsorbent regeneration and As recovery using NaOH. EXAFS results demonstrate that As(III), as the only As species present in the raw water,

Arsenic in Complex Orebodies Ausenco

The selective flotation of enargite from copper sulphides in a complex ore system is discussed in this paper. Methodology and Results. A complex ore system was selected which had various levels of arsenic as enargite. Two ore samples with different arsenic levels, HAS (250 ppm) and LAS (100 ppm), were selected to provide a range of arsenic level.

Arsenic removal from copper ores and concentrates through

Sep 01, 2009· Ore samples were first prepared by crushing and grinding followed by sizing of both ores and concentrates to obtain size ranging from 35 to 75 mm for the leaching experiments. Samples with arsenic content below 1.0 wt.% were also blended with enargite ore with arsenic content over 8.0 wt.% to obtain a composite with arsenic content of 3.0 wt.%.

The Role of Arsenic in the Mining Industry

[8] The majority of the arsenic released by all sources end up in the soil and the ocean. [8] Since valuable metals such as copper and gold can also be found in sulfide mineral deposits, mining exploration companies will often look for soil and water with a naturally high arsenic content as a means of locating an ore

THE ALKALINE SULFIDE HYDROMETALLURGICAL SEPARATION

A proprietary gold recovery process has been adopted to quantitatively and selectively recover gold from complex alkaline sulfide solutions containing a mixture of metals such as arsenic, tin, mercury and antimony. This is illustrated by selectively removing gold from an alkaline sulfide leach solution containing these impurities. The assay of

Arsenic Ores Article about Arsenic Ores by The Free

Arsenic ores are divided into several known types according to the commercial classification of ore deposits: arsenic (arsenopyrite and realgar-orpiment), gold-arsenic, complex-metal-arsenic, copper-arsenic, arsenic-cobalt, and arsenictin ores. Commercial ores contain a maximum of 2 percent As, but ores with a 5–10 percent As content are

US3709680A Process for removal of arsenic from sulfo-ore

A process and apparatus for the removal of arsenic values from an ore concentrate includes the steps of leaching the concentrate with a solution which dissolves the arsenic, separating undissolved residue therefrom, acidifying the arsenic pregnant solution to precipitate arsenic and other mineral values as insoluble salts and treating the arsenic barren solution to regenerate sulfur and sodium

Arsenic Centers for Disease Control and Prevention

Arsenic Arsenic is a naturally occurring element that is found in combination with either inorganic or organic substances to form many different compounds. Inorganic arsenic compounds are found in soils, sediments, and groundwater. These compounds occur either naturally or as a result of mining, ore smelting, and industrial use of arsenic.

Devon Great Consols Wikipedia

The post-war slump brought an end to mining tungsten and tin at Devon Great Consols, but arsenic production continued until 1930. [10] [c] Some copper precipitation and ochre recovery took place at the mine at the midpoint of the 20th century and a small mill was built for the purpose of treating the site's dump ore, [10] [32]

Arsenic Minerals Education Coalition

Most arsenic is obtained not from an ore mineral of arsenic, but as a by-product in the treatment of gold, silver, copper, and other metal ores. Environmental laws require that arsenic be removed from ores, so that it does not enter the environment in effluent gases, fluids, or solids.
