PROCESS MINERALOGY

HOW OUR LAB WORKS

Dr Navin K Sharma Process Mineralogy Laboratory (Experts in Process Mineralogy) is well prepared to accept your mineral processing test samples and mineralogical programs at a competitive price with high quality to reduce risk and add value to operation through:

  1. Characterization of ore and process mineralogical assessment

  2. Statistical Validation of Plant Trials and mineralogical attributes

  3. Mineralogical evaluation for Plant Support, Start-up and Consulting.

  4. Metallurgical Accounting 

Outsourced Geometallurgical Studies

  1. A complete Metallurgical (Ore to Metal) evaluation of simple / complex, mono or multimetal ores, contain copper, lead, zinc, silver, cobalt, gold, tungsten, tin,  iron, chromium (in the form of carbonate, sulphate, silicate, hydrosilicate, hydroxide, oxide, sulphosalts or sulphide etc) . We are capable to provide mineralogical characterization of phosphates, rare earths, beach sands or any industrial minerals. We will define detailed mineral proportion, chemical composition of ore with photomicrographic and textural evidences in order to serve client up to utmost satisfaction with followed by discussions.

  2. Similar studies are being offered for clients facing problems such as changes in ore mineralogy and their liberation characteristics , services Also extends for Processing of beach sands other than rock samples.

  3. Contouring of petro graphic/physical mineralogical and chemical properties

  4. Defining the variation in physical and chemical, variability (internal dilution) within the ore body.petro graphic

Outsourced Process Mineralogy

  1. Prediction of Grind / Comminution Optimization - Crushing and Grinding Circuits for defining the best fit Mesh of Grind. Bench scale test for optimization of MOG (Mesh of Grind) for complex multimetal ores, containing copper, lead, zinc, silver (silicate, hydroxide, oxide and sulphide) containing phosphates, rare earths, beach sands, tungsten, tin or iron.

  2. Characterization of feed i.e., cyclone overflow and underflow/combine and feed to flotation.(Image Analysis, Granulometry, XRD, Chemical Mineralogy)

  3. Geometric assessment of free and locked mineral / s of concentration, degree of liberation, multiple/complex lockings status up to an extent of 5 microns.

  4. Optimum prediction for best Granulometric assessment of minerals of interest

  5. Define the degree of textural intricacy of the inherent economic/gangue minerals by the study of feed to ball/rod mill fractions.

  6. Sieve fractions studies and correlation of individual mineral species.

  7. Characterization of base metal/multimetal (lead, zinc, silver, copper) flotation products by using mineral liberation data. Floatability, misplacement, tailing losses etc. Assessment of Magnetic, electric, density properties.

  8. Base line studies of rougher concentrate to mineral kinetics and misplacement phenomenon for prediction of grade and recoveries for lead, zinc and copper concentrate.

  9. Bulk concentrates studies for optimization of concentration.

  10. Misplacement and liberation characterization of individual concentrates in order to optimize the metallurgical equilibrium

  11. Suggestion for utilization/performances of newly designed mineral processing equipment / processing software tools.

  12. Quantification and cause of loses in running operations and remedial suggestions for plant performance improvements. 

  13. Gravity, MGS and Physical Separations and Process Troubleshooting

  14. Flow sheet Development in Base metals, Tin, Tungsten and Industrial minerals.
