UGPL PROCESS TECHNOLOGY AUSTRALIA
High Density Separation-UGPL-Particle Accelerator Diffusion
Non-Cyanide Mineral Extraction Processing
Renovare and UMACO Pty Ltd Unite to
Introduce New Extraction Process
UGPL Precious Metals Process:
The (UGPL) Gold Process is designed with High Density Separation-UGPL-Particle Accelerator Diffusion in a Non-Cyanide Mineral Extraction Processing Lixiviate disacharide. The process will be introduced to Australia by UMACO Pty Ltd. We at UMACO have invested our professional mining and exploration expertise to bring to you the very latest in technology.
UGPL is a unique environmentally friendly gold extraction process that replaces cyanide solutions with a proprietary innovation and lixiviate (solution). The rest of the gold mining process remains virtually the same. The chemical agents used in the Gold Process are available in large quantities, and the capital equipment requirements are quite modest.
UGPL can work with both high and low grade ores but always uses tanks not heap leaching. And the UGPL responded to the conventional procedure of recovering the gold from solution using activated carbon or Merrill-Crowe. The UGPL is particularly effective with micro-fine gold and, when appropriately modified, it’s effective with refractory ores where cyanide does not work.
A technology for processing gold ores that offers various advantages over present techniques.
The process extracted gold in bulk and in significantly less time than is possible with cyanide.
Recovery rates were exceptionally good, particularly when compared to cyanide on the ores tested.
The process responded to the conventional procedure of recovering the gold from solution using activated carbon.
The process does not require any exotic equipment or hardware, or pose unusual engineering problems in the design or fabrication of a commercial plant.
Handling requirements for the chemicals used are significantly less stringent than those practiced for cyanide. This should simplify waste disposal.
In the tests observed, the process extracted 80% of the gold from a low grade ore from a district of Colorado and 93% of the gold in a high grad ore concentrate from an area of California. In both instances, leach time was completed in
6 hours.
An Australian ore sample from the Hodgkinson Province, sample number A101 (the lowest sulfur value ore sent), had a UGPL extraction efficiency of 99.3% and extractin time was approximately 3.5 – 4.5 hours.
ELECTRODEPOSITION OF METALS
- Historically, 2D cells, such as tank or plate-and-frame cells are suitable for bulk metal removal, but they cannot meet stringent recovery or treatment standards.
- Development efforts have been directed towards finding high surface area, stationary electrode materials.
- Testing shows that low concentrations of metals can only be achieved with reasonable current efficiencies by using porous 3D electrodes.
Cell improvements in electrochemical cell performance focused on:
- Obtaining high active cathode surface areas that allow compact design and efficient conversions even at low metal concentrations.
- High Current efficiency to minimize energy usage.
- High current density to effect rapid metal removal.
- Intimate contact between electrolyte and electrodes to provide high mass transport.
- Ease of production removal.
- Safety and ease of control.
- Lower operating costs
DIVIDED CELLS
Dividers are used to separate the cathode from the anode and thus create an electrochemical reactor for advanced applications.
Two types of dividers are available:
- Porous material that act as a physical barrier
- Ion-select membranes that are highly selective, permitting the transport of only of either cations or anions and accompanying solvent.
Dividers are used when anode reactions must be controlled, (e.g. chlorides and chlorine generation), control anode corrosion (e.g. fluorides), control undesirable reactions (e.g. iron ‘shuttle’), control impact of anodic reactants (oxygen).
