METHODS AND SYSTEMS FOR OPERATING VEHICLES TO REDUCE BUNCHING

Abstract

Systems and methods of operating vehicles to reduce bunch- ing of the vehicles when traveling on a roadway determine an intra arrival time for two consecutive vehicles traveling on the roadway; calculate a virtual spacing between the two consecutive vehicles based on the intra arrival time; deter- mine a following distance threshold; compare the virtual spacing between the two consecutive vehicles with the following distance threshold; determine that the two con- secutive vehicles are in a bunched condition when the virtual spacing between the two consecutive vehicles is less than the following distance threshold; and control at least one of the two consecutive vehicles until the vehicles are no longer in the bunched condition.

Title

METHODS AND SYSTEMS FOR LEACHING A METAL-BEARING MATERIAL

Abstract

Methods for recovering a metal value from a metal-bearing material are provided. The method comprises agglomerating the metal-bearing material with an agglomeration solution comprising a raffinate, an oxidant, and citric acid or salts thereof to form an agglomerated metal-bearing material; leaching the agglomerated metal-bearing material with a leaching solution comprising the raffinate and the citric acid or salts thereof to produce a pregnant leaching solution and a leached material; re-oxidizing the leached material with a curing solution comprising the raffinate and the oxidant; and recovering the metal value from the pregnant leach solution to produce the raffinate.

Title

ACID MIST SUPPRESSION IN COPPER ELECTROWINNING

Abstract

A method of acid mist suppression in copper electrowinning is described. In various embodiments, at least one liquid licorice root extract, powdered licorice root extract, or reconstituted licorice extract is added in an amount sufficient to the acidic electrolyte solution of the copper electrowin- ning process to suppress acid mist from the acidic electrolyte solution during the copper electrowinning process. In vari- ous embodiments, combinations of licorice extract and surfactant show synergies in acid mist suppression during copper electrowinning.

Title

SYSTEM AND METHOD FOR ADJUSTING LEACHING OPERATIONS BASED ON LEACH ANALYTIC DATA

Abstract

The method may comprise receiving historical data (e.g., mineralogy data, irrigation data, raflinate data, heat data, lift height data, geographic data on ore placement and/or blower data); training a predictive model using the historical data to create a trained predictive model; adding future assumption data to the trained predictive model; running the forecast engine for a plurality of parameters to obtain forecast data for a mining production target; comparing the forecast data for the mining production target to the actual data for the mining production target; determining deviations between the forecast data and the actual data, based on the compar- ing; and changing each of the plurality of parameters from the forecast data to the actual data to determine a contribu- tion to the deviations for each of the plurality of parameters.
