How to Separate Copper from Lead by Cu Depression
How you separate Pb from Cu depends on how much of each metal is present. You best depress the metal that’s the most present, the metal you have the most of & you float the metal you have the least of. In this case, flotation of a small amount of lead from the copper concentrate would maximize copper recovery, while removing
Rock Crusher History
History tells us, it was in 1830, the first US patent was issued on a rock crushing machine. It covered a device which, in a crude way, incorporated the drop hammer principle later used in the famous stamp mill, whose history is so intimately linked with that of the golden age of mining. In 1840, another patent was issued, which comprised a wooden
What Ore Testing is Required For Mill Selection
Beginners might ask what grinding test data is required in order to properly size a grinding mill. After the grind requirements are established, testing for the selection of comminution circuits and mill size can be initiated and can include the following: Primary Autogenous Media Competency Primary Autogenous and Semi-Autogenous Pilot Plant Secondary Autogenous (Pebble) Testing Impact Crushing – Bond Work
Copper Assay Method Review
If we review the Code 8-Peroxide ICP-Sodium Peroxide Fusion ICP (Sodium peroxide fusion, acid dissolution followed by ICP/OES) This method is fine for the copper total assay. That is all that should be used for the balances of flotation tests. If taking the copper sulphide number (Cu(s)) ie: the total copper number and subtracts the “copper oxide” assay you create a

Flotation Foam
Table of ContentsFOAM EFFECT The process depends upon the fact that minerals with a metallic lustre, when treated in the form of a wetted pulp, adhere to oil, while earthy minerals do not. Two distinct operations are involved; first, the separation of the metallic mineral from the gangue by means of oil; second, the extraction of the mineral from the
Measure and Evaluate Flotation Tail Losses
In this example, the losses of chalcopyrite to the copper scavenger tail is equivalent to about 10 percent of the copper in the ore. Losses of liberated chalcopyrite are minimal accounting for less than 1% of the copper in the feed. Most of these losses occurred as grains sized smaller than 14µm in equivalent diameter. About 55% of the copper losses to the scavenger

Galvanox Copper Leaching Process
The following is a description of the testing procedure for scoping studies for candidate Galvanox Process materials and concentrates. This document will cover both the procedure for individual tests as well as considerations and strategies for testing regimes. Galvanox testing regimes will be different depending on the mineralogy, grade, particle size distribution, pyrite:chalcopyrite ratio and gangue level of the
Mineralization of Greenstone and Mesothermal Deposits
What does a Greenstone/Mesothermal shear zone hosted Mineralization deposit look like? Well they usually comprise one or more steeply dipping quartz or carbonate rich veins, as you can see in the pictures these sometimes forms veins or even stock works of narrow vein. Mineralization is regularly distributed in the vein often forming steeply plunging high grade. All rock alteration is seldom
Porphyry Copper Deposit Geology PPT
Here let’s understand the geology of porphyries and iron oxide copper gold deposits or IOCG as they are known. These are somewhat the giants of the ore deposits world. As a mining interested learner, the geology of porphyry copper deposits is vital to your education. Now in the first Exploration Geology Course I discussed how because our current mining technology all
Monster Patch for KK-8 Melting Furnace Kiln
We offer another product for repairing the liner after a serious spill. Monster Patch is made up of alumina silicate fibers in a thick, moldable, super sticky base that can be applied up to ½” thick at a time. Monster Patch is a bit difficult to work with, however the material can be thinned with hot, distilled water, which makes
KK-8 Kiln Furnace Liner Maintenance
Three products are supplied with the KK-8 for optimizing and extending the life of the kiln liner: Liner Restore, Armor Coat and Spill Stop. All three products must be kept from freezing, or they will become unstable and unusable. Restored Kiln Sections Liner Restore is an alumina silicate based viscous material that is designed for filling cracks and patching any
How to Fire-Start KK-8 | Initial Firing & Break-in Proceduce
As previously mentioned in the introduction, the insulation comprising the lining of the kiln is composed of a micro-fiber alumina silicate refractory material. Under a microscope, these fibers resemble quartz crystals and, when heated to the temperatures the kiln operates at, a portion of these fibers fuse together. When the fibers fuse together, some of the voids between the fibers
Starting OR Firing the Small KK-8 Propane Furnace Kiln
Step 1. Place the kiln on a sturdy, level, fireproof surface. A minimum of 2’ x 3’ is necessary for the kiln, burner and pyrometer. The kiln is a modular design and comprised of three pieces; the base, the body and the lid. The body and lid are removable together or separately and allow for easy loading and removal of
Propane Melting Furnace Kiln – Small Fire Assay Furnace
Propane Melting FurnaceThe burner supplied with the KK-8 is unique in its design and is comprised of a bi-metal construction. The burner is constructed of mild steel with a brass nozzle tip in order to eliminate the corrosive environment created by the use of a conventional steel or stainless steel burner nozzle with the kiln. When a conventional steel
Calculate a Mill’s Operating Work Index
Use this online formula to calculate a Ball Mill, Rod Mill or SAG Mill Operating Work Index. Based on Fred Bond’s work you can estimate the energy used into your grinding circuit. This is the most accurate and informative method, but much of the data necessary for its application is not yet available. A) Total Apparent Volumetric Charge Filling –
