SNS corpus is a sample collection of the real language. 1) Language materials in the corpus should be taken from the real texts actually used.
Corpus collection, choose the appropriate language materials to prepare corpus annotation in advance.
In general, the language materials usually choose strong interest，strong literary flavor，colorful emotional expression language.
Corpus annotation system refers to the degree of processing on the language materials.

Therefore, development of approaches for extraction of valuable metals from flotation tailings is relevant issue as it may allow not only producing valuable metals from waste materials but also decreasing harmful effect on environment.
Leaching with ferric iron solutions is promising method for treatment of different raw materials including slags and substandard concentrates [9, 11, 12].
Materials and Methods Samples of old pyrite flotation tailings and copper-zinc concentrate obtained at an industrial concentrators in Russia were used.
Thus, old flotation tailings may be used not only as source of non-ferrous metals but also for obtaining ferric iron solutions, which can be used for oxidative leaching of different raw materials.
