Metals Tools and Machines
Metals play an important part in modern societies and have historically been linked with industrial development and improved living standards. Inefficient recovery of metals from the economy increases reliance on primary resources and can impact nature by increasing the dispersion of metals in ecosystems. Though the practice of recovering metals for their value dates back to ancient civilizations, today, the protection of Earth’s resource endowments and ecosystems adds to the incentive for recovering metals after use.
Industrial society values metals for their many useful properties. Their strength makes them the preferred material to provide structure, as girders for buildings, tails for trains, chassis for automobiles, and containers for liquids. Meats are also uniquely suited to conduct heat (heat exchangers) and electricity (wires), functions that are indispensable to industrial economies. Finally, metals and their compounds are used for their chemical properties as catalysts for chemical reactions, additives to glass, electrodes in batteries, and many other applications.
Metals can be recycled nearly indefinitely. Unlike polymer plastics, the properties of metals can be restored fully, though not always easily, regardless of their chemical or physical form. Nevertheless, the ability to recover metals economically after use is largely a function of how they are used initially in the economy and their chemical reactivity. The success of secondary metals markets depends on the cost of retrieving and processing metals embedded in abandoned structures, discarded products, and other waste streams and its relation to primary metal prices.
Demand for scrap metals depends on industry structure and the availability of production technologies that accommodate scrap feeds to yield value added products. The complex market relies on the decisions of many independent actors including scrap dealers, brokers, dismantlers, and smelters.
METALS PRODUCTION FROM PRIMARY AND SECONDARY RESOURCES
Metal production begins with either primary or secondary resources. Primary resources, or ores, contain relatively high concentrations of metals and are generally found at depths up to 1 kilometer beneath the surface. Secondary sources include all metals that have entered but no longer serve a purpose in the economy. For metal producers, the choice of whether to use primary or secondary sources is determined primarily by the type and capacity of existing capital equipment, quality of the feed, metal prices, and relative supply.
Secondary metal supplies fall into two general classes, new and old scrp. The former refers to metal discards generated within an industrial setting, either at metals producers or from metals fabricators. Because new scrap stays within the mill or factory, the quality (i.e., chemical composition) is generally well known and homogeneous. As a result, this metal readily returns to the production loop. Old, or obsolete, scrap refers to metal collected after use in the economy in the form of discarded infrastructure, industrial equipment, or consumer goods.
Environmental Impacts of Metal Production
One of the most striking environmental benefits of secondary metals productions is the reduction in energy needed to produce a ton of metal. The primary reason for this phenomenon is that melting metal requires less energy requirement for producing a ton of aluminum, copper, and steel starting from ore or scrap. Steel produced from primary ore uses three and one half times more energy than steel from melted scrap. Copper from ore requires five to seven times more energy than that required for processing recycled metal as this ratio rises with decreasing ore grade. Aluminum from ore uses approximately twenty times more energy than from recycled metal.
In addition to conserving energy resources, metals recycling also reduces mining and beneficiation activities that disturb ecosystems.
The Niton XL3t GOLDD+ XRF analyzer
With the Niton XL3t analyzer which is a spectroscopic using laser light reflecting from a piece of metal, the mixed metal scrap is automatically sorted into streams containing aluminum, zinc, and copper alloys, as well as stainless steel and lead. The use of automated systems that rely on these various methods for alloy separation should increase scarp throughput as well as scrap quality and thus help society process more of the metal currently discarded.
