Developing a relationship between ore feed grade and flotation performance
… impact plant performance. The depletion of high-grade ore deposits has posed the mining industry with the challenge of processing much more complex, low-grade ores to meet the growing demand of metal production for our technologically driven future. A fundamental understanding of mineral …

An in vitro assessment of the effects of feed-grade trace minerals on commercial phytase activity
… to increase the nutritional value of animal feeds through the hydrolysis of phytate-bound phosphorus. Inorganic trace minerals (ITM) routinely added to feed can negatively impact phytase activity. Recent research has shown that replacement of ITMs with organic trace minerals (OTMs) may …

Effects of Supplementing Crystalline L-Valine and L-Isoleucine and a Novel Threonine Biomass in Reduced Crude Protein Diets fed to Broilers
… continue to identify methods to lower feed price without compromising broiler growth performance, processing yields, or animal well-being. A common approach is to reduce dietary crude protein (CP), the second most expensive component in a broiler diet. Subsequently, reducing CP will …

Reducing Dietary Crude Protein: Characterization of Branched-Chain Amino Acid Antagonism in Modern Broiler Chickens
… has involved supplementing broiler diets with feed-grade amino acids and proving the economic benefits of their additions. To date, widespread adoption of feed-grade amino acids is limited to methionine, lysine, threonine, and to some extent valine. With valine and isoleucine gaining prevalence …

Analyses of organic grain prices
… Dairy farms seemed to pay a lower premium for feed grade corn and hard red winter wheat compared to other types of buyers. Buyers located in Kansas tended to provide a smaller premium than buyers located elsewhere. Early contract periods produced a smaller premium than later periods. Shipment …

Towards the development of an integrated modelling framework underpinned by mineralogy
… recipe that converts chemical assays to mineral grades. The EMC technique has the advantage of being fast, inexpensive and can be used on a routine basis. The recipe for this specific polymetallic sulfide ore was designed to calculate nine minerals in four different rounds, using least square …

The use of simple analytical techniques to assess surface oxidation of sulphide ores
… oxidation makes it more difficult to process low-grade sulphide minerals, which reduces the recovery of valuable minerals during flotation. It may be possible to quantitatively correlate the rate/level of oxidation to oxidized sulphide ores using simple surface analytical techniques. This, if done …

Methodology for evaluating the digestibility and metabolizable energy of poultry feedstuffs
Determining the energy values of feed ingredients for poultry is of great concern, especially since production efficiency is associated with profit margins. Therefore, accurate, precise, and reproducible energy values for feed ingredients are of the utmost importance in formulating an economical …
