Recovering and Recycling Landfill Fly Ash

Coal-fired power plants in the United States generate about 75 million tons of coal ash annually. Compared with the 267 million tons of trash that Americans generate per year, it

Beneficiation and mineral processing of bauxite and feldspar

Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain.

ST Equipment & Technology uses electrostatics to produce value-added feed coproducts from the ethanol industry

As margins on ethanol products tighten or disappear, many ethanol producers choose to focus on value creation from coproducts. Dried distillers grains with solubles (DDGS) has long been an undervalued

The Benefits of ST Equipment & Technology’s Process For Very Fine Dry Iron Ore

Iron ore is the fourth most common element in the Earth’s crust and is generally extracted by way of open-pit mining operations. Recovering high-grade iron ore is a relatively simple

The Benefits of Fly Ash in Ready-mix Concrete

Fly ash is the mostly mineral residue left over from burning coal by coal-fired power plants. Fly ash is pozzolanic, meaning that it has cementitious properties that make it valuable

An Opportunity For Ethanol Producers To Improve Margins

According to a report from the Energy Information Administration, operating margins for corn-based fuel ethanol plants decreased to a multi-year low in 2019. This was due in part because production

Dry beneficiation of bauxite minerals for greater yields

The primary starting material for aluminum refining is bauxite. Since aluminum is a reactive element and does not occur naturally, aluminum-rich ore needs to be refined to produce alumina and

Trends in using plant protein for aquaculture feed

Using plant-based proteins to supplement fish meal has been a part of aquaculture for decades. Fish feed comes from harvesting fish species such as anchovies, herring, menhaden, and sardines. The

A water-free protein enhancement process for distillers grains

Dry Distillers Grains (DDG) and Dry Distillers Grains and Solubles (DDGS) are a nutrient-rich co-product of the ethanol production process. Both are also a valuable food source for the livestock
