FIELD: precious metal recovery. SUBSTANCE: thread is formed by a core consisting of at least one threadlike member that is wrapped around by a spiral of threadlike member consisting of platinoid group metal or platinoids alloy. Threads are joined by weaving, knitting, sewing, and embroidery to form catalysts, and means to recovering and catching particles of precious metals and their alloys. These can also be used in production of nitric acid and hydrocyanic acid. EFFECT: enabled new catalytic layer structures and new parameters for construction. 34 cl, 8 dwg
