Abstract: Processes, compositions and kits are provided for suppressing generation of acid mist in an electrowinning process. The processes include the step of adding a powder of lignosulfonate or a derivative thereof or an aqueous solution comprising lignosulfonate or a derivative thereof to an electrolytic solution of the electrowinning process in an amount sufficient to suppress generation of acid mist without formation of foam at an upper surface of the electrolytic solution. The kits include instructions for carrying out the processes.

Abstract: A method includes receiving a request to execute a particular workload of a plurality of workloads at a distributed computing system that includes a plurality of clusters. Each workload of the plurality of workloads includes respective workload characteristics. The method also includes determining a workload key for the particular workload based on the respective workload characteristics of the particular workload. The method also includes obtaining a workload history based on determining the workload key and, for each respective cluster of the plurality of clusters, determining a corresponding score associated with executing the particular workload at the respective cluster based on the workload history. The method also includes executing the particular workload at one of the plurality of clusters based on the corresponding score of each respective cluster of the plurality of clusters.

Abstract: A composition for suppressing generation of acid mist in an electrowinning process. The composition includes about 1.5% to about 20% (m/m) of a C2 to C6 organic acid, about 15% to about 35% (m/m) of a diphenyl oxide disulfonate or diphenyl oxide sulfonic acid compound; and about 20% to about 30% (m/m) of a plant root extract containing a triterpenoid saponin. Methods for preparing the composition and using the composition in an electrowinning process are also described.
