Colloidal silica can also be used as a reference material for both particle size and zeta potential. Ludox TM silica is a well known and characterized colloidal material that has been studied using various particle size analysis techniques including acoustic spectroscopy, laser diffraction and dynamic light scattering.
Oil sands mining operations are some of the largest mines in the world. Although open-pit oil sands mines have a lot in common with traditional hard-rock mines (such as gold or copper), oil sands operators have some unique challenges due to the softness of the deposit. Learn more about surface mining techniques used in the oil sands.
Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Ironsand also known as iron-sand and iron sand is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight,
Silica Sand. Ashapuras rounded to sub-rounded shaped silica sand grains (Supsil and Castsil) are naturally suitable for glass and foundry applications.
