The state of and prospects of technology development of ore preparation and enrichment of chrysotile asbestos ores at JSC "Kostanaiskie Mineraly" are observed. Much attention is paid to the process of homogenization of the mineral, it is carried out in the quarry via management of ore streams in the formation of a warehouse of raw ore, at intermediate warehouses.
After deleting outliers and setting the classes into PCA, the spectral signatures of the reference samples were thus utilized to generate the calibration dataset for the SIMCA model. More in details, three components for chrysotile and amosite and five components for crocidolite were selected. The same preprocessing utilized for PCA was applied.
Thorough inspection of appliances before plugging in, the use of dust proof outlets in the areas designated for fibre processing as well as protective gloves will reduce the risk of this occurrence. If wet processing carbon fibre or composite materials takes place only air driven or intrinsically safe equipment for wet processing is to be used.
chrysotile, as well as among the general population living in the neighbourhood of asbestos factories and mines and in people living with asbestos workers (7). The incidence of asbestosrelated diseases is related to fibre type, size and dose and . to industrial processing of the asbestos (6). No threshold has been identified for the

A process for inactivating industrial wastes of chrysotile asbestos which has the peculiarity of consisting in subjecting the industrial wastes of amianthus or fibrous chrysotile asbestos to heating at a temperature no lower than 580 o C to eliminate the water present in the molecule and convert the fibrous chrysotile asbestos into forsterite.

Currently, it produces ~20% of the world's chrysotile. Mining and processing of raw chrysotilecontaining ore have been undertaken at this site since the late 19 th century (Zorina and Kashansky, 1999). At Uralasbest's openpit mine, chrysotile is mined through a mechanized process of drilling and blasting (Kashansky et al., 2001).

Asbestos is a broad term embracing a number of fibrous silicate minerals. These minerals look extremely fragile, yet their fibers have a tensile strength equal to that of piano wire. Chrysotile asbestos is the only mineral that can be woven into cloth, and its fibrous structure is, if anything, even more amazing than its remarkable ability to withstand heat. Chrysotile asbestos from Quebec ...
