Chromite Beneficiation Process
The Problem with Chromite Processing. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed ...

Reprocessing - EVE University Wiki
Compressed ores require 1 unit to process, while uncompressed ores require 100 units. You cannot process uncompressed ores with less than 100 units of a single type, e.g. 75 units of Veldspar cannot be combined with 25 units of Dense Veldspar for processing. Both compressed and uncompressed ores yield the same amount of minerals per batch.

How Ore Sorting Leads to Mineral Processing Success
Vibrating screens help improve ore sorting by removing fines from the circuit while also sending large particles back to the cone crusher. This makes a double-deck vibrating screen an ideal choice for ore sorting as this single piece of mineral processing equipment can accomplish both of these tasks.
