Study of quartz grain-size characteristics by computer image analysis
With use of the computer program of Image Tools have been studied studying of granulometric characteristics of quartz of various structural types of reference deposits of Southern Ural. It is shown, that the average size of grains of quartz of «kush- timskogo» type lays in interval of 1,4-1,6 mm, «ufaleiskogo» type - 0,8-1 mm, «egustinskogo» - 0,2-0,4мм. It is established, that 0,1-2 mm grains constitute main portion in quartz of all structural types. It is established that the maintenance of basic elements - impurity in quartz concentrates of a vein № 414 are close to values characteristic for quartz of mark IOTA of firm Unimin whereas the maintenance of impurity in quartz concentrates of a vein Berkutinskaya exceeds these values for a number of elements.
