The fundamental element in the capture process is the interaction between a small magnetisable particle, usually paramagnetic, in a uniformly applied magnetic field (Watson, 1973, Watson, 1998).Consider a ferromagnetic wire of radius a and a saturation magnetisation M s placed axially along the z axis as shown in Fig. 1.A uniform field H 0 large enough to saturate the wire is applied in the x

The present invention relates to the decontamination of soil and the like and, in particular, soils which are contaminated with metal as a result of the activities of human beings. The invention provides a physical and a chemical means for treating soil aggregate so as to obtain a product aggregate having a relatively low metal content.
The Gangcha gold deposit was discovered in 2011 in the Xiahe Hezuo region, West Qinling Orogen, China. Five types of pyrite have been identified in the ore
The conversion process for light water reactors involves converting UO 3 to uranium hexafluouride (UF 6), a chemical form suitable for enrichment. During this process, the UO 3 is combined with fluorine compounds to create UF 6. Video animations of the refining and conversion processes are available on the Cameco Corporation channel on YouTube
Apr 29, 20160183;32;In this process, Zn is added in molten Pb because of high affinity of Zn for Ag and Au than Pb. Then two liquid layers such as Liquid Zn at the upper layer having Zn% of 0.6 Liquid Pb at the bottom layer having Pb% of 1.5 As Zn layer (first layer) has higher melting point. So, solidify first. 44.
Chapter 23 The d Block Elements. Chapter 21 quot;Periodic Trends and the quot;and Chapter 22 quot;The quot;described the chemistry of the s block and p block elements.In this chapter, we survey the chemistry of the d block elements, which are also called the transition metals.We again use valence electron configurations and periodic trends, as well as the principles of chemical bonding, thermodynamics,
Plumbogummite is a rare secondary lead phosphate mineral. It was discovered in 1819 and named in 1832 from the Latin 'plumbum' for lead, and 'gummi' for gum, in allusion to its lead content and appearance, which at times resembles coatings of gum.

The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore.The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can beprocessed and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or
