17 Guidelines for Nonferrous Scrap INSTITUTE OF SCRAP RECYCLING INDUSTRIES, INC. Copyright © 2018 Institute of Scrap Recycling Industries, Inc. Zebra (High Density) Shall consist of high-density nonferrous metals pro- duced by media separation technology containing brass, copper, zinc, nonmagnetic stainless steel, and copper wire. Material to be dry and free from excess oxidation. The percentage and types of metals other than these, as well as the percentage and types of nonmetallic contamination, are to be agreed upon between the buyer and seller. Zeppelin(Light Density) Shall consist of light-density nonferrous metals pro- duced by media separation technology and contain thin-gauge aluminum and magnesium. Material to be dry and free from excess oxidation. The percent- age and types of metals other than aluminum and magnesium, as well as the percentage and types of nonmetallic contamination, are to be agreed upon between the buyer and seller. Zeyda SHREDDED INSULATED COPPER WIRE Shall consist predominantly of recovered ICW (Insu- lated Copper Wire) that has been derived by either mechanical or physical separation. This material is likely to have other metals, in small percentages (should be less than 5%) that were not successfully separated. The percentage of each metal within the overall product shall be subject to agreement between buyer and seller. Shall have passed one or more magnets to reduce or eliminate free iron and/ or large iron attachments. Shall be free of radioac- tive material, dross, or ash. Material to be bought/ sold under this guideline shall be identified as “Zeyda” with two numbers to follow, indicating the estimated percentage recoverable copper wire and the second indicating the maximum amount of other metals or contaminants expected. (e.g., “Zeyda 45/3” means the material contains approximately 45% copper and up to 3% other material). May also be screened to permit description by specific size ranges. Zorba SHREDDED NONFERROUS SCRAP (predominantly aluminum) Shall be made up of a combination of the nonfer- rous metals: aluminum, copper, lead, magnesium, stainless steel, nickel, tin, and zinc, in elemental or alloyed (solid) form. The percentage of each metal within the nonferrous concentrate shall be subject to agreement between buyer and seller. Material generated by eddy current, air separation, flota- tion, screening, other segregation technique(s), or a combination thereof. Shall have passed one or more magnets to reduce or eliminate free iron and/or large iron attachments. Shall be free of radioactive material, dross, or ash. Material to be bought/sold under this guideline shall be identified as “Zorba” with a number to follow indicating the estimated percentage nonferrous metal content of the mate- rial (e.g., “Zorba 90” means the material contains approximately 90% nonferrous metal content). May also be screened to permit description by specific size ranges. (Refer also to Zorba under Aluminum.) Zurik SHREDDED NONFERROUS SENSOR SORTED SCRAP (predominantly stainless steel) Shall be made up of a combination of the nonfer- rous metals: stainless steel, insulated copper wire, aluminum, copper, lead, magnesium, nickel, tin, and zinc, in elemental or alloyed (solid) form. The percentage of each metal within the nonferrous concentrate shall be subject to agreement between buyer and seller. Material generated by computer sensing equipment (e.g., induction sensor sorting or X-ray) technique(s). Shall have passed one or more magnets to reduce or eliminate free iron and/or large iron attachments. Shall be free of radioactive material, dross, or ash. Material to be bought/sold under this guideline shall be identified as “Zurik” with a number to follow indicating the estimated percentage nonferrous content of the material (e.g., “Zurik 90” means the material contains approxi- mately 90% nonferrous metal content). May also be screened to permit description by specific size ranges. (Refer also to Zurik under Nickel/Stainless/ Hi Temp.) OTHER HEAVIER PIECES OF ANY SIZE, LENGTH, AND WEIGHT ACCEPTABLE UPON MUTUAL AGREEMENT BETWEEN BUYER AND SELLER. Ranch BLOCK TIN Block tin must assay minimum of 98% tin, and to be free of liquids, solder, and brass connections, pew- ter, pumps, pot pieces, and dirt. Ranks PEWTER Shall consist of tableware and soda-fountain boxes but should contain a minimum of 84% tin. Siphon tops to be accounted for separately. Material must be free of brass, zinc, and other foreign metals. Raves HIGH TIN BASE BABBITT Shall contain a minimum of 78% tin and be free of brassy or zincy metals. Roses MIXED COMMON BABBITT Shall consist of lead base bearing metal containing not less than 8% tin, free from Allens metal, orna- mental, antimonial and type metal. Must be free from all zinc and excessive copper in the alloy. Identification Checklist for Precious Metals This Identification Check List for Precious Metals sets up a general basis for identifying types and grades of precious metals scrap by the scrap processor who will be familiar both to the precious metals refiner and to the plants gener- ating precious metals scrap. By checking this identification list, the scrap processor gives the refiner a fairly accurate conception of the material the processor has on hand and offers a basis for the refiner to quote an estimated price for the material.
