Extractive Metallurgy & the Smelting of Bronze
Extractive Metallurgy & the Smelting of Bronze INTRODUCTION: Seven metals were in use before the invention of writing: gold, silver, copper, iron, mercury, tin & lead. Many of these are so scarce they couldn’t be used practically (like gold). Others are rarely found in their elemental form, instead found as minerals of carbonates, oxides, or sulfides. It is the elemental form of metals that we are familiar with when we speak of their shiny, malleable and conducting properties. As minerals or ores, metals exist in combination with other elements, often as brittle, non-conducting substances (image rocks, salts & crystals). To produce a metal in its elemental form from an ore requires a chemical transformation, a process of extractive metallurgy called smelting. The fundamental problem of smelting involves the chemical reduction of metallic compounds to elemental metals, with different compounds requiring different treatment conditions. Oxide or carbonate ores are heated with charcoal, which combines with the oxygen in the ore, to release carbon dioxide and produce the elemental metal. 2 Cu3(CO3)2(OH)2 + 3 C → 6 Cu + 7 CO2 + 2 H2O (1) SnO2 + C → Sn + CO2 (2) Copper was the earliest metal to come into common usage because its ores are fairly common, like that of malachite (Cu2CO3(OH)2), and because it can be smelted at moderate temperatures (see equation 2 above). It is a soft metal, however, which makes it of marginal value for tools and weapons. Tin forms an alloy with copper, called bronze, which is harder than either metal alone. By 3,000 BC bronze had become the dominant metal, so much so that its use defines the Bronze Age.

I. Principles of Extractive Metallurgy
I. PRINCIPLES OF EXTRACTIVE METALLURGY RAKES H KUMAR Email : [email protected] Extractive metallurgy as a discipline deals with the extraction of metals from naturally occurring and man made resources. Separation is the essence of metal extraction. Development of efficient separation schemes calls for a through understanding of extractive metallurgy principles in terms of physical chemistry (thermodynamics & kinetics); materials and energy flow/balance, transport phenomena, reactor and reactor engineering, instrumentation and process control, and environment and waste management. (Slide 1-4) In general, metallurgical separation processes involves chemical reactions, and classified as pyrometallurgical, hydrometallurgical, and electrometallurgical. The processes are also classified as ferrous [dealing with iron and steel] and nonferrous [dealing with all other metals, e.g. base metals (like Cu, Pb, Zn, Ni, ...), light metals (Al, Mg, Ti), precious metals (Au, Ag, Pt, Pd, ...), rare earth (Ce, Nd, Sm, ...), nuclear metals (U, Th, ...), rare metals (Os, Ru, ...) etc]. (Slide 6) Various pyrometallurgical unit processes are: calcination, roasting, smelting, converting, refining, distillation etc. Each of these processes serves a specific purpose from the point of view of separation. They require specialized reactor depending upon the phases (solid/liquid/ gases) involved, mode of contact, temperature, environmental measures etc Calcination and roasting are used as pre-treatment prior to other pyro- and hydro- metallurgical operations. (Slide 7, 8) Smelting is the most common of pyrometallurgical operations. Reduction smelting is carried out for oxides. During the smelting, metal compound (e.g. oxide of metal) is reduced to metallic form, and the undesirable impurities (gangue) combine with flux to form slag. Immiscibility of metal and slag together with density difference forms the basis for separation.

Extractive metallurgy is the branch of metallurgical science & engineering which deals with the extraction and refining of metals from ores. An ore is a rock that contains commercially viable amounts of metallic/non-metallic solid minerals. Ores are complex associations of mineral grains A mineral is a chemical compound that constitute a component of an ore, and with its own characteristic chemical composition. Introduction – Types of Ores & Minerals Most metals are combined with other elements to form minerals. Few exist as pure metals.

Pyrometallurgy and Electrometallurgy of Rare Earths – Part A: Analysis of Metallothermic Reduction and Its Variants
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 18 March 2021 doi:10.20944/preprints202103.0463.v1 Page 1 of 14 Pyrometallurgy and electrometallurgy of rare earths – Part A: Analysis of metallothermic reduction and its variants Muhammad Musaddique Ali Rafique Eastern Engineering Solutions Inc., Cambridge, MA 02139 E: [email protected] Abstract Rare earths are classified as most important and critical material for US economy and defense by Congress and a mandate has been set to increase their in-house production, domestic resource utilization and decrease reliance on foreign resources and reserves. They are widely available in earth crust as ore (bastnaesite (La, Ce)FCO3, monazite, (Ce, La, Y, Th)PO4, and xenotime, YPO4), but their so-called economic reserves are sparsely located geographically. They may be produced by various means such as beneficiation (physical, chemical, mechanical, or electrical), reduction (direct or indirect), electrolysis (of aqueous or molten / fused single or mixed salt systems) at high temperature or hydrometallurgy. Out of these, direct reduction also known as metallothermic reduction (La and Ca reduction) is mostly utilized. Its variant, high temperature electrowinning of fused salts is also practiced widely. These processes are material and application specific. In this study, author will employ thermodynamics (Ellingham diagrams, -2 free energy of formation, reduction potential, Nernst equation, Pourbaix (Eh-pH) diagrams, E-pO diagrams), kinetics and energetic of a chemical reaction (chemical metallurgy) to reduce rare earth oxide / salt to rare earth metals (REO/RES – REM). It is shown that materials and energy requirement vary greatly depending on type of mineral ore, production facility, and beneficiation / mineral processing method selected.
