The extraction of silver by the solving processes simple. The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely. After roasting, the ore is first subjected to leaching with water, in order to extract the base metal chlorides, and then with hyposulphite of lime, to extract the silver.

Jul 01, 2007· The two DNA extraction methods ([SDS-CTAB]-method and Mobio kit) gave a DNA-yield very similar from the basalt rock sample (between 0.35 and 0.55 ng/g crushed rock; Fig. 3) and lower than the yield obtained from the positive control sample, particularly with Mobio kit (3 μg DNA/g soil). However, although the DNA-yield was similar with the both ...
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
