METHOD OF SALVAGING AUTOMOTIVE TIRES AND WASTES OF ORE MINING AND SMELTING Russian patent published in 2010 - IPC C08J11/00 C08L21/00 C10L5/10 

FIELD: process engineering.

SUBSTANCE: invention relates to briquetting of mineral resources, secondary raw material and can be used in metallurgy, machine building etc. Proposed method comprises preparing automotive tire to accumulate wastes to be salvaged, blending and filling said tire. Mix of said wastes has the following composition in wt %: fines of coke - 24, crushed tires - 5-10 mm-fractions - 10, blast-furnace dust - 10, oxide scale of electric filters - 40, blast-furnace or steel-smelting, sintering tails - 10, buhr - the rest. Note here that CaO/SiO₂≈0.7-0.8 that corresponds to basic capacity of slag in acid process. Mix in tire is compacted on vibration table. Filled tires are loaded in metallurgical installation, backfilled by sinter, and tires are transferred into reducing process zone. Device to implement above described method comprises tire to accumulate aforesaid wastes. There is a hole to load wastes inside the tire made in tire outer surface. Inner slot of the tire is covered by wood or metal rim.

EFFECT: higher efficiency of salvaging.
