Steel-making: the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulfur, phosphorus and silicon. These have to be removed. Removal of sulfur: Sulfur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulfide.
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 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.
The technology of production of BCF (Basalt Continuous Fiber) is a one-stage process: melting, homogenization of basalt and extraction of fibers. Basalt is heated only once. Further processing of BCF into materials is carried out using "cold technologies" with low energy costs.

In fact, supercritical CO2 extraction is already a standard extraction method for the food, dry cleaning and herbal supplement industries. It is a common food additive as well. The CO2 extraction process allows compounds to be extracted with low toxicity; it utilizes a high pressure vessel containing cannabis.
Jan 01, 2016· Extraction with Supercritical Gases. In general, conventional extraction methods such as steam distillation and solvent extraction have been traditionally used; however, these methods have disadvantages such as low yield, loss of volatile compounds, long extraction times, and toxic solvent residues (Khajeh et al., 2005).This has led to the development of alternative extraction techniques .
Extraction is a very common laboratory procedure used when isolating or purifying a product. Organic chemistry employs solid-liquid, liquid-liquid, and acid-base extractions. The following applies to liquid-liquid extractions, which will be used in this course.

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.
