AbstractAbstract
[en] The concentration of beryl has been mainly investigated to develop a product as good as the ''hand-cobbed'' mineral used in the extrative metallurgy of beryllium. The purpose of this paper is to show a review of the concentration of beryl by cationic and anionic flotation depicting their principal aspects. (author)

AbstractAbstract
[en] A study was made of the variation in the number of spots in a sunspot group for the groups of the maximum area, 200 Ssub(max) 500 millionth parts of the solar hemisphere area, (m. p. h.) and Ssub(max) 50 m. p. h.. The data are presented on the measurement of the average rated number of sunspots with time for three group subclasses. The results give indications that the probability of a regular evolution (variation in the number of group sunspots) is not high, and the majority of the groups are of irregular evolution nature
