Diaphragm Pump Working Principle
To begin, let’s start the description with the Diaphragm Pump and its Working Principle. The name of the diaphragm pump is derived from the RUBBER MEMBRANE that the pump uses to achieve its pumping action. The diaphragm works on an air displacement principle. The membrane is mechanically pushed and pulled in and out of a pumping chamber. When the diaphragm
Pumps in Mineral Processing
The pumps in a mineral processing concentrator (plant) can roughly be classified into two groups, PROCESS pumps and SERVICE pumps. A service pump is any pump that provides a service to the process. A Process pump is one whose function is part of the process. The pump doing this type of job will be directly responsible for maintaining the CONTINUOUS
Types of Ore Deposits

Komatiite-associated nickel deposits Layered mafic-ultramafic intrusion deposits Skarn deposits Fractionated granitoid-associated deposits Porphyry-associated deposits Iron oxide copper gold deposits Syn-deformational hydrothermal and replacement deposits Orogenic gold deposits Carbonate-hosted stratabound lead-zinc deposits Unconformity-related uranium deposits Volcanic-associated massive sulphide deposits Sediment-hosted stratiform base metal deposits Sediment hosted copper deposits
Hydrocyclone Working Principle
The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE. Unlike the rake and

Spiral Classifier for Mineral Processing
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry

Table of ContentsRake ClassifierParticle ClassificationStraight RAKE ClassifiersHow to Control a Rake Classifier Let me describe a cycle of the Rake Classifier arm to you. The arm, with a series of rakes along its length, drops into the flow of slurry and is pulled upwards. Some of the fine material will flow over, the top of the rake. The rest will
Screw Classifiers
To be successful in a obtaining a uniform grind that is necessary to achieve a high percentage of recovery it is necessary to control the degree of fineness that the ore is reduced to. This is done by separating the fine material from the course and regrinding the coarse until it is fine enough for efficient mineral extraction. To be
Grinding Circuit and Mill Safety
Grinding circuits are made up of large, moving pieces of machinery. When carrying or moving objects in and around this equipment extreme care should be taken. As an example, when operating the crane, never hoist anything directly over the mills. If it is necessary to take long pieces of material, like pipes and lumber in between or around this
Ball Mill Circulating Load
The concept and theory to best understand a Ball Mill Circulating Load is shown here as an excerpt from Arthur and Ball mill circulating load PPT Circulating load based on pulp density Circulating load based on screen analysis
Operating and Troubleshooting a Grinding Circuit
In the operation of a grinding circuit you are managing several pieces of equipment as a single unit. If you make a change in the ore in the fine ore bin, that change will be reflected through the entire grinding process and beyond into the rest of the concentration system. The first thing that an operator will have to learn
Hydrocyclone Operation
The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the “OVERFLOW” via a Vortex Finder. The mineral that still requires grinding is named the “UNDERFLOW” via the Apex Finder. These two terms, the “overflow” and “underflow”
Operating a Grinding Circuit -Understand Your Flowsheet
The next thing that I would like to discuss is the operation of the circuit as a unit. The CIRCUIT is the common name obtained from the path that the ore takes as it progresses through any particular process. In this case grinding. I won’t deal with start-up procedure as it will change from mine to mine depending on the
Grinding Mill Liners
Table of ContentsGrinding Mill Rubber LinersRubber & Steel Combination Liners There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result

Rod Mill Liners
Among the cast materials used for linings are Ni-Hard. chrome-molybdenum steel, and manganese steel. Rolled alloy steel plate with lifter bars is available Rod mill liners are subjected to severe impact. Premature breakage and scrap loss are reduced by correct selection of liners for the specific gnnd-mg duty. Additional benefit results from use of a backing material, such as rubber between
Cyanide Free Gold Leaching Alternative
What is cyanide and why do we need cyanide-free gold leaching process? Cyanide (CN–) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H2O) to form a gold cyanide complex (Na [Au(CN)2] ) and sodium hydroxide (NaOH). The chemical reaction dubbed the “Elsner Equation”, named after
Ball & Rod Mill Density – How Water Impacts Grinding
Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper
Grind Calibration Curve -Laboratory Test
Before doing multiple laboratory flotation bench tests in which you need P80 grind controlled or predicted, you need to build a Grind Calibration curve following this short procedure. You will consistently add sufficient water to the mill to achieve a pulp density of 67% solids (Example: 1 kg solids + 0.5 kg water or 2 kg solids + 1 kg water.)
