Gravity Tests

Gravity tests, also known as gravity separation tests, are used to determine if a constituent, especially gold, can be concentrated by exploiting differences in density, shape, and or size between the constituent of interest and the waste material (gangue). 911 Metallurgy specialists have extensive experience in gravity processing and can provide you with the gravity concentration services you need.

Why use gravity concentration?

Gravity concentration is often an effective and economic unit operation, with low capital and operating costs. The process can also be environmentally favorable, as little to no reagents are used in the process. 911 Metallurgy can help you determine if your ore process could benefit from gravity concentration.

What are the different types of gravity test equipment available?gravity tests

There are many different types of equipment that can be used for gravity separation including but not limited to:

  • Cyclone Separation
  • Dense Media Separation
  • Hand Panning
  • Falcon Concentrator
  • Knelson Concentrator
  • Jigging
  • Spirals
  • Wilfley Tables

911 Metallurgy specialists have extensive experience with all types of gravity concentration equipment and will help you optimize your process with the equipment best suited to your ore.

What is a gravity test?

Gravity test procedures can vary depending on the type of equipment being used. Generally, a known amount of material is processed by the gravity concentration equipment, resulting in a concentrate and tailings product. The concentrate and tailings are then weighed, dried, and assayed to determine final constituent mass balances and recoveries. 911 Metallurgy specialists have experience with all types of equipment and will tailor your testing program based on your ore.

How can I optimize recoveries?

Gravity separation recoveries are often significantly impacted by the feed size of the material. Additionally, 911 Metallurgy specialists can also provide extended gravity recoverable gold testing and gravity process circuit modeling.

Flotation Tests

Flotation tests are used to evaluate a materials amenability to froth flotation processing. 911 Metallurgy can provide you with the flotation processing test work that you need, at both the laboratory and pilot plant scale.froth flotation tests

What is flotation?

Flotation is a process that is used to concentrate a constituent or remove a constituent by exploiting and manipulating the hydrophobic and hydrophilic properties of material.

Can my ore/material be floated?

Flotation can be used on a variety of ores including oxide, mixed, and sulfide ores. 911 Metallurgy specialists can help you determine if flotation is an effective processing strategy for your project. Our specialists have experience developing flotation strategies for various ore types including but not limited to ores that contain rare earth oxides, precious metals, base metals, and iron ore.

What is a flotation test?

A known amount of ore and water is added to create a slurry. Next, reagents are added to change the surface properties of the material. Then, chemicals called collectors are added to the slurry to form hydrophobic surfaces on the constituent of interest. Air or nitrogen is then bubbled through the agitated slurry. The air bubbles come into contact with the hydrophobic surfaces, transporting them to the surface, where they form a froth or foam. The foam is then separated from the pulp, creating a concentrate. The concentrate and tailings are then weighed, dried and assayed, to determine final constituent mass balances and recoveries. During the test, reagent additions are also tracked so that reagent consumption’s can be determined.

How do I optimize my flotation process?

911 Metallurgy helps you optimize your flotation process by considering important parameters such as  grind size, reagent selection, reagent optimization, and kinetics. Our specialists have decades of experience running rougher, cleaner, kinetic, locked cycle, and pilot scale flotation tests.

Column Leach Tests

Column leach tests or column percolation leach tests, are primarily used to simulate heap leach conditions. 911 Metallurgy has comprehensive column leach testing and heap leach experience, and can provide you with guidance and service to meet your projects needs.

What is heap leaching?          

Heap leaching is a common mineral processing technique, used to extract precious metals (Au and Ag), copper, uranium, and other constituents. First, ore is stacked onto an impermeable plastic liner. Then, a solution containing reagents, specific to the targeted constituent or constituents, is dispersed using a drip or sprinkler system. The solution percolates through the heap, extracting constituents by dissolving them. The enriched solution, called the pregnant leach solution or PLS, is then collected and processed to extract the constituent of interest.

Already in production, but need help?

No problem, 911 Metallurgy can help you solve problems with your heap. 911 Metallurgy can provide comprehensive on-site or off-site services.

What are column leach tests?

Column leach tests are used to evaluate if a constituent or constituents can be extracted from a solid, under simulated heap leach test conditions. First, the solids are sized according to the needs of the test work. Then if needed, column test feeds are agglomerated to improve the permeability and strength of the stacked feed. A leach solution is then applied to the top of the column, at a constant flow rate. As the solution percolates through the column it dissolves and concentrates constituents into a pregnant leach solution (PLS). The PLS is collected daily, to track reagent consumptions, interim constituent concentrations, and to determine final constituent mass balances and recoveries. Tests are often run until pregnant leach solution constituent concentrations approach detection limits, to determine maximum recoveries, with leach cycles ranging from months to years.

Need help managing or designing your testing program?

911 Metallurgy has years of experience managing and designing heap leach testing programs. Our specialists will walk you through the entire process from preliminary testing (e.g. ore characterization and coarse bottle roll tests), to geotechnical testing (e.g load permeability testing), to optimization (e.g. crush size and reagent), to extraction (e.g. solvent extraction), to design.hydrometallurgy

Bottle Roll Tests

Bottle Roll Tests

Bottle roll tests are widely employed in metallurgical and environmental testing. 911 Metallurgy has extensive bottle roll testing experience and can provide you with guidance and service to meet your laboratory testing needs.

What are bottle roll tests?

Bottle roll tests are used to evaluate if a constituent or constituents can be removed from a solid through dissolution. Basically, known amounts of solid and liquid are added to a bottle, to create a slurry. The slurry is then gently agitated and sampled at scheduled time intervals, to track reagent consumptions, interim constituent concentrations, and to determine final constituent mass balances and recoveries.

Metallurgical Applications

In metallurgical testing, bottle roll tests are used to determine a materials amenability to leaching a specific metal or metals. Tests can be run at coarse feeds to evaluate heap leaching amenability, or fine feeds to evaluate conventional mill leaching processes.

Reagents specific to the type of metal or metals targeted are added to the bottle roll test solution. Solutions can vary from acid, to neutral, to basic. Cyanide is typically used to extract precious metals, such as gold and silver. Whereas, solutions containing sulfuric acid are often employed to extract copper.

Don’t know what conditions or reagents to use?

No problem, 911 Metallurgy specialists can provide you with the knowledge you need, even for less common reagents and processes.

Environmental Applications

In environmental applications, bottle roll tests are used to characterize what constituents might impact the environment when a solid material is exposed to a solution. Particularly, if the constituent will become harmful if it migrates into a source of water, such as a river, lake, or aquifer.
