Trona mining and Soda Ash production

We only produce Soda Ash from naturally occurring underground ore, called trona, which is more environmentally friendly than alternative synthetic production methods, which use significantly more energy and water, and produce significantly more CO 2 and solid waste. We operate the three lowest cost production facilities in the world – at Eti Soda and Kazan Soda in Turkey, …


The invention relates to a process for recovering precious metals from fine carbon bearing residual amounts of precious metals. The process involves the incineration of the carbon, followed by a method for separating the precious metals from carbon ash. Possible methods include cyanidation, gravity concentration, smelting, electrowinning and solvent extraction.

Our facilities

Processing. The surface plant converts trona ore to soda ash in a multi-step purification process. First, the trona ore is precision crushed and screened to prepare it for processing. View image. The crushed trona is heated in a kiln to drive off unwanted gases. This heating process transforms the ore to crude sodium carbonate.

What is Soda Ash?

 · Soda ash, also known as sodium carbonate (Na2CO3), is an alkali chemical refined from the mineral trona or naturally occurring sodium carbonate-bearing brines (both referred to as natural soda ash), the mineral nahcolite (referred to as natural sodium bicarbonate, from which soda ash can be produced), or manufactured from one of several chemical processes …

Soda ash processing method

 · In the described application relating to trona ore processing, heat loss is preferably minimized to prevent premature crystallization of soda ash product and resulting product loss. When the level of filtrate in the top exceeded the height of the filter vessel's weir, the filtrate spilled over the weir and gravity flowed through a flow-metered
