Lesson 1: Concepts of Metallurgical Analysis Flashcards
the application of analytical-chemical methods to chemical problems of metallurgy, including problems of valuation and utilization as well as production.
Metallurgical Analysis
the quantitative estimation of the metals in ores and furnace products
Metallurgical Analysis
WHY DO WE ASSAY ORE/MATERIALS?
-as basis for the estimation of material’s commercial value
-to determine the material’s fitness or adaptability to a certain use
-serves as guide in the operation of a process or in determining the efficiency of a process or treatment
4 commercial’s value
- Price of Metal ($/tons) – LME metal prices
- Volume (m^3) – strike x depth x width
- Specific Gravity – Table of S.G. for different minerals
- Grade – obtained from assay result
burned for steam to run turbines to generate electricity either to public electricity grids or directly by industry consuming electrical power (such as chemical industries, paper manufacturers, cement industry and brickworks).
Thermal Coal or Steaming Coal
used in the process of creating coke necessary for iron and steel-making.
Metallurgical Coal or Cooking Coal
porous, hard black rock of concentrated carbon that is created by heating bituminous coal without air to extremely high temperatures.

CHOOSING THE BEST ASSAY TECHNIQUE
Accuracy
Cost
results are demanded to be the most accurate in the time allowed
Accuracy
If only approximations to a fair degree of accuracy are demanded
