Patent CA-2952642-A1 (CA)
Title: Flotation of sphalerite from mixed base metal sulfide ores either without or with largely reduced amount of copper sulfate addition using 2-(alkylamino) ethanethiols as collectors
Inventor: NIRDOSH INDERJIT
IPC: B03D1/012
Filed: 2016-12-22
Abstract: The main objective of the invention was to develop a new flotation collector that could eliminate or reduce the amount of copper sulfate used in the flotation of sphalerite. Different series of collectors such as cupferrons, arylhydroxamic acids and amino mercaptans or amino thiols were synthesized and tested. Amino mercaptans/aminothiols were found to be very effective in floating sphalerite from a lead-zinc ore using only 10-15% of copper sulfate used with conventional xanthate collector. The present invention does not require any alteration in the current mill practices. This warrants only changing the flotation collector in zinc flotation stage from, for example, potassium amyl xanthate (PAX) to the new collector.

Title: Systems and methods for creating and using a research map
Inventor: SHARMA SANJAY
IPC: G06Q50/18
Filed: 2011-12-08
Abstract: Systems and methods create a graphical representation of a research map that allows performance of search functions using the nodes of the graphical representation. In one implementation, a system includes a processor and a memory. The memory stores instructions that cause the processor to receive a query for searching a document repository and run the query in the document repository. The processor stores the results of the query and the query as a root node in a research tree. The processor receives a filter for the results of the query. The processor stores the filter and the result list for the filter as a filter node connected to the root node of in the research tree. The processor receives a request to view a document from the result list for the filter and stores the request as a document node connected to the filter node. The processor then creates a display of a research map that includes the research tree.
