    Analiza powiązań pomiędzy parametrami technologicznymi pras walcowych z wykorzystaniem analizy czynnikowej
    (Wydawnictwa AGH, 2010) Saramak, Daniel
    Chosen issues concern the multi dimensional analysis and their potential application for modeling of comminution processes in roller presses were presented in the article. The comminution process in HPGR can be described with using many technical and technological parameters and indices, which are mutually connected. The presented approach assumes the investigation over the structure of analyzed variables, and presents the interpretation consisted in marking off the factors related to the input variables (operating parameters of the comminution process). The model characterizing the issue, obtained as a result of research, makes easier the interpretation of the process under analysis.

    Wstępne badania geochemii talu i arsenu w rudach Zn-Pb Górnego Śląska
    (Wydawnictwa AGH, 2009) Kucha, Henryk; Rajchel, Bernadeta
    Upper Silesian Zn-Pb deposits contain toxic elements, such as: thallium and arsenic. Basing on data from literature (Harańczyk 1965), factor analysis was performed for: Ag, As, Cd, Fe, Mn, Pb, S, Tl, Zn. This analysis showed that ores have to be present new minerals, which contain arsenic and thallium. Following detailed mineralogical research defined a new oxysulphide mineral - $(Fe_{1.8}Pb_{0.1}Zn_{0.1})_{2}SlO_{5}$.
