What is Soda Ash?

Sourced from underground. Used in products worldwide.

What is Soda Ash?

Soda Ash is the 10th most consumed inorganic compound in the world, which has been used for over 5,000 years. It is a safe, simple compound and a key component in a variety of industrial processes from the manufacture of glass to dry powder detergents and lithium-ion batteries. It is also an important ingredient in the food and pharmaceutical industries.

Life’s invisible ingredient; Sodium Carbonate, Na2CO3
The ancient Egyptians recovered Soda Ash from dry dessert lake beds or produced it by burning marine plants with high sodium content to produce ashes, which gave the commonly used name of ‘Soda Ash’. They used it to reduce the melting point of silica sand to produce glass vessels and ornaments – the same basic production technique used in glass manufacturing today. The Romans also used its related compound, Sodium Bicarbonate, for medicinal purposes and to make bread.

Successive generations produced Soda Ash in this way until the mid-1800s, when synthetic production techniques were first developed, to supply the increasing demand from an industrialising world.

How is Soda Ash made?

Today, Soda Ash (Sodium Carbonate) is produced by two main methods, both of which produce chemically identical Soda Ash.

  1. Natural Soda Ash production: Natural Soda Ash is produced by mining naturally occurring Trona ore and then processing this via a simple process of filtering, concentration, crystallisation and drying into Soda Ash which can be sold. Today, this accounts for around 33% of global production. Commercially exploitable Trona deposits only occur geologically in three regions of the world: Enormous deposits in Wyoming, USA, large deposits in Turkey and much smaller and chemically less pure deposits in China. 

  2. Synthetic Soda Ash production: By synthetic production methods using either the so-called Solvay or Hou processes, in which salt (sodium chloride) is reacted with either limestone or ammonia to produce synthetic Soda Ash. This accounts for about 67% of global production.

Eti Soda only produces Soda Ash from naturally occurring trona

HOW WE MINE TRONA?

Conventional mining

Traditionally, underground trona was mined using conventional underground mechanical mining.

 This mining technique has been used extensively in Wyoming by all producers of natural Soda Ash since the 1960s, including at our Ciner Resources facility.

Once the ore has been mined using continuous mining machines at the working mine face, shuttle cars transport the ore to conveyors which then take the ore to a central mine shaft where it is lifted to the surface.

Solution mining

First developed at Eti Soda, we are the only company in the world to use innovative solution mining technology to extract trona ore.

We use this at both our Eti and Kazan facilities. This patented production method injects heated water into the underground ore body, which then dissolves the trona forming brine solution. The brine is then extracted to the surface, and pumped to a central processing facility.

This closed loop system is safer (no underground operatives), has minimal impact on the surface, uses significantly less energy and water than other production methods and also produces significantly less CO2 emissions.

Where is Trona found?

Trona has been found in lake brines or naturally occurring mineral deposits. Trona (a mix of water, sodium bicarbonate, sodium carbonate and sometimes sodium chloride or salt) is the most common and richest source of naturally occurring Soda Ash.

While Trona occurs naturally in a few locations worldwide, the largest and purest deposits are found near Green River, Wyoming, USA and near Ankara, Turkey.
