WO1991005068A1 - Convection elution - Google Patents

An apparatus and method for elution by convection of an adsorbed material, such as gold adsorbed in activated carbon. The convection elution apparatus comprises a vessel (26) provided with a top screen (28) and a bottom screen (30) defining a compartment (32) therebetween within which the activated carbon is retained during the elution process.

Extracting Gold | HowStuffWorks

This causes gold to collect on the negative terminals. ­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers

Gold | Geoscience Australia

Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.

Elution - Wikipedia

Elution then is the process of removing analytes from the adsorbent by running a solvent, called an "eluent", past the adsorbent/analyte complex. As the solvent molecules "elute", or travel down through the chromatography column, they can either pass by the adsorbent/analyte complex or they can displace the analyte by binding to the adsorbent in its place.

A Poor Man's Method of Smelting Gold | Sciencing

Smelting gold usually involves high-tech and high-cost tools to perform. Mostly, mining companies do the procedure, which sees one material bonded to or released from another in the presence of extreme heat. However, prospectors, and people at home, can smelt their old gold using some simple steps.

Gold extraction - Wikipedia

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

The Metallurgy of Cyanide Gold Leaching – An Introduction

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

US5051128A - Elution process for gold-iodine complex from

A process for eluting gold-iodine complex from an ion-exchange resin, characterized by adding sulfuric acid and sodium nitrite to the gold-iodine complex adsorbed on the resin, and adding sodium sulfite as an eluant. The process is particularly useful for eluting gold-iodine complex adsorbed on strongly basic anion-exchange resin, such as washings resulting from the washing of leach residue

List 10 Types of Solids, Liquids, and Gases

Gases become liquids; liquids become solids. On the other hand, increasing temperature and decreasing pressure allows particles to move father apart. Solids become liquids; liquids become gases. Depending on the conditions, a substance may skip a phase, so a solid may become a gas or a gas may become a solid without experiencing the liquid phase.

Electrowinning - an overview | ScienceDirect Topics

Recognized methods of elution of strong-base resins use zinc cyanide, ammonium thiocyanate, or acidic thiourea. Although each method has advantages and disadvantages ( Fleming and Cromberge, 1984 ), no single method seems to be appropriate for all cases. For example, Fleming (1989) used the zinc-cyanide method for a conventional strong-base resin (A161RIP) used at the Golden Jubilee RIP plant, while for a more selective resin such as Minix, the thiourea method is more effective.
