Metal and Non-Metal Mining

Bulk material handling is a field in engineering centred on the design of equipment used for the handling of dry materials.

SN Lavalin, as one of the biggest suppliers in the manufacture and design of bulk handling equipment and independent plant-wide systems, is committed and well-versed in producing top-notch individual and automated systems that will discover Metal and Non-Metal Mining bulk materials from exterior and interior plant sites, move it between processing machinery and storage facilities, ascertain its weight, feed it to packaging lines, extrude it, mould it and finally store.

Methods of Processing

Below are standard methods for Metal and Non-metal Mining processes, which involve carrying powder and bulk ingredients.

  • Crushing

Crushing is the first step of mineral processing. The ore/rocks from the mine site are fed into the mechanical equipment to reduce the size of masses for subsequent usage by liberating the gangue’s valuable mineral.

  • Dewatering

Dewatering is the action of removing groundwater from a mine. dewatering is fundamental to the viability of the mine and may require the use of substantial resources and management

  • Excavation

Excavation is the artificial creation of cavities in the earth’s crust through the extraction of rock created to open mineral deposits, transport minerals, and ventilate mines.

  • Pelletizing

It is used throughout many industries to process thousands of materials from difficult to handle powders and fines into easy to handle pellets.

Other processes include Drying, Packaging, Screening, Separating, Flotation, Leaching, Filtration, etc.

Bulk Material Features

Bulk materials from metal and non-metal mining range from abrasive to dusty, non-free-flowing to free-flowing, and powders to large pieces. Common material types are:

  • Texture

These materials tend to be very rough.

  • Moist

Sometimes these ingredients can be slightly wet.

  • Lumpy

Bulk material ingredients are also characterized by lumps covering them.

As stated earlier, bulk materials can be free-flowing and non-free-flowing.

Common Bulk Materials Handled

In this industry, common bulk materials that are used include

  • Bentonite

This is an absorbent swelling clay consisting mainly of montmorillonite. The main uses of bentonite are in the drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides.

  • Kaolin

Kaolin is also called china clay, soft white clay that is an essential ingredient in china and porcelain manufacturing and is widely used to produce paper, rubber, paint, and many other products.

  • Titanium Dioxide

Titanium dioxide, also known as titanium (IV) oxide, is the naturally occurring titanium oxide. When used as a pigment, it is called titanium white or Pigment White 6. It is widely used to make paint.

Other popular materials include Rutile, Sand, Urea, Magnesia, Alumina, Fire clay, Fire ash, etc.

Tips to Satisfy Your Bulk Handling Needs

• Fill or discharge containers
• Off-load and load tankers, railcars, and trucks
• Move ingredients from single or multiple sources/destinations
• Ascertain the weight of the batch, then blend automatically
• Cut the cost of labour while promoting safety
