Hand sorting mineral processing

Bulk ore sorting improves profitability and sustainability ...

A bulk ore sorting system, on the other hand, is much simpler, less expensive and has a much smaller footprint than the current individual particle sorting technologies available. The additional costs associated with bulk ore sorting are likely to be outweighed by the reduction in either downstream processing costs or by the increase in production.

Sensor-Based Sorting Technology - LTH

Sorting has been used in mineral processing since the Stone Age and until modern time sorting has been carried out by hand to sort out val-uable material from unwanted ma-terial. During the twentieth century ore grades and liberation sizes de-creased, the scale and economics of processing operations changed, and new technology was intro-duced.

Mineral processing | metallurgy | Britannica.com

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Sorting - Wikipedia

Various sorting tasks are essential in industrial processes. For example, during the extraction of gold from ore, a device called a shaker table uses gravity, vibration, and flow to separate gold from lighter materials in the ore (sorting by size and weight).Sorting is also a naturally occurring process that results in the concentration of ore or sediment.

Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Diamond Processing Flow Chart of Beneficiation

This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands.
