A Dry Metric Tonne (Ton) Unit (dmtu) is the internationally agreed-upon unit of measure for iron ore pricing. It has the same mass value as a metric tonne, but the material has been …
Dry Metric Tonne Unit
Dry Metric Tonne Unit. A Dry Metric Tonne (Ton) Unit (dmtu) is the internationally agreed-upon unit of measure for iron ore pricing. It has the same mass value as a metric tonne, but the material has been dried to decrease the moisture level. A dry metric ton unit consists of 1% of iron (Fe) contained in a tonne of ore, excluding moisture.
Ore, Rock & Aggregate Screening (Complete Guide)
A-Z Guide to Screening Ore, Rock & Aggregate A simple definition of a "screen" is a machine with surface(s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface". Knowledge of …

Introduction to Iron ore Pellets and Pelletizing processes
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 …
Beneficiation
Crushing is a dry operation which only involves dust control using water spray (Drzymala, 2007). A primary or jaw crusher is located at the mine site and reduces the particle diameter of the ores into <6 in. The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration.
Dry and Wet Screening in Mining: What are the Differences?
If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter
