NCBI Bookshelf. This chapter outlines the basic steps involved in mining, processing, and reclamation that might be suitable for uranium ore deposits in the Commonwealth of Virginia. For uranium ore deposits, the choice of mining methods and processing options is very deposit-specific and dependent on many variables such as the quality and quantity of the ore, the shape and depth of the ore deposit, site-specific environmental conditions, and a range of other factors. Accordingly, the description of how uranium mining is undertaken in this report is generalized and at a high level.
The state of the art for the recovery of metals from steel industry by-products using hydrometallurgical processes is reviewed. The steel by-products are different slags, dusts, and sludges from a blast furnace BF , basic oxygen furnace BOF , electric arc furnace EAF , and sinter plant, as well as oily mill scale and pickling sludge. The review highlights that dusts and sludges are harder to valorize than slags, while the internal recycling of dusts and sludges in steelmaking is inhibited by their high zinc content. Because wide variations in the mineralogical composition and zinc content occur, it is impossible to develop a one-size-fits-all flow sheet with a fixed set of process conditions. The reason for the interest in EAF dust is its high zinc content, by far the highest of all steel by-products. However, EAF dust is usually studied from the perspective of the zinc industry. In many chemical processes, only the ZnO dissolves, while the ZnFe 2 O 4 is too refractory and reports to the residue.

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations , and other factors.

Hydrometallurgy is a technique within the field of extractive metallurgy , the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Hydrometallurgy is typically divided into three general areas:. Leaching involves the use of aqueous solutions to extract metal from metal bearing materials which is brought into contact with a material containing a valuable metal.
Источник их находился где-то совсем близко. Сьюзан поворачивалась то влево, то вправо. Она услышала шелест одежды, и вдруг сигналы прекратились.
Отсюда я не в состоянии ему помочь - ему придется полагаться лишь на. А потом, я не хочу говорить по линии, не защищенной от прослушивания. Глаза Сьюзан расширились.
Мы будем ждать. Джабба открыл рот. - Но, директор, ведь это… - Риск, - прервал его Фонтейн.
Мы ищем различие, выражаемое простым числом. Через несколько секунд всем стало ясно, что эта затея бессмысленна. Числа были огромными, в ряде случаев не совпадали единицы измерения. - Это все равно что вычитать апельсины из яблок, - сказал Джабба.
Этим рейсом улетели несколько пассажиров, купивших билет перед вылетом. Но мы не имеем права сообщать информацию личного характера… - Это очень важно, - настаивал Беккер. - Мне просто нужно узнать, улетела ли. И больше .
