In the complex production required to transform spodumene concentrate into lithium compounds such as lithium carbonate or lithium hydroxide, calcination plays a key role in not one, but two parts of the process, making it an essential technique in efforts to exploit this increasingly important …
Organic combustion is the thermal treatment of organic wastes with the intent of reducing mass and volume. This process is frequently seen in waste treatment plants in order to reduce the volume of organic wastes for deposit into landfill. Organic combustion leaves behind an ash …
The rotary kiln is a diverse thermal processing device capable of carrying out a variety of process objectives, from burning off volatile components to activating carbon, and more. As a substantial investment, those looking to purchase a rotary kiln must make every effort to avoid …
The lithium-ion battery market has seen explosive growth in recent years, largely in response to the growing electric vehicle market, coupled with the increasing use of consumer electronics and a desire to advance energy storage technology for renewable energy applications. A Grand View Research report …
Kaolin clay, also known as China clay, is an essential industrial mineral primarily made up of the mineral kaolinite – a hydrous aluminum silicate. Kaolin can be found in applications all around us, from consumer products, to advanced industrial processing. Most notably, kaolin is lauded …
This week’s photo highlights a ball and tube knocking system. Knocking systems are often implemented to combat build-up inside of a rotary dryer. The systems are usually externally fitted on the inlet end of the dryer, where the incoming material is most wet and sticky. …
Expanded clay aggregates, also called exclay, or lightweight expanded clay aggregates (LECA), are a beneficial material in a growing number of industries – most notably construction and horticulture, with water treatment and filtration applications likely next in line. The unique structure and physical properties of …
Biochar, a charcoal-like, carbon-based material with roots in ancient civilizations, has scientists excited over the potential it holds for restoring depleted soils, improving food security, and aiding in climate change efforts when used as a soil amendment. What is Biochar? Biochar is created through the …
Our photo this week shows a batch rotary kiln test conducted in the FEECO Innovation Center. The batch kiln is used to simulate the conditions of a continuous, commercial rotary kiln. The kiln is lined with a lightweight castable refractory and heated with a propane burner. …
Cyanidation, or the metallurgical process of extracting gold from ore with cyanide leaching agents, has long been a primary method of gold beneficiation. Widely used throughout the world, one incredible material helps to make gold recovery from a cyanide solution possible; with its ultra-porous structure, …
