Title: Process for the selective recovery of lead and silver
Inventor: ALVAREZ CARRENO CARLOS
IPC: C22B7/00
Filed: 2014-09-26
Granted: 2021-11-30
Abstract: Abstract The present invention relates to a process for the selective and ecoefficient recovery of lead and silver jointly as a concentrate product from metallurgical residues. The main advantage over the state-of-art is that concentrates of silver and lead can be recovered simultaneously from metallurgical residues in only three overall steps including a purification step that can reduce the content of chloride contaminants to as low as 0.01% on a dry weight basis. This method avoids further metal separation steps and represents an economically viable process to selectively obtain silver and lead in one concentrate without the need for high-cost equipment.

Abstract: In a deviated wellbore, a pump system computes downhole data from surface data by solving a wave equation that takes both viscous damping and Coulomb friction into consideration. Mechanical friction between the rods, couplings, and tubing is considered in the calculation of downhole data in the deviated wellbore by modelling the wellbore's trajectory, parameterizing various deviated segments (build-ups, slants, drop-offs, etc.) in the trajectory, mapping the rod string to the segments, and incrementally evaluating position of the mapped string over time in order to compute drag forces and side loads experienced by the rod string during operation. These computed drag forces and side loads are then used in the solution of the wave equation to solve the surface load and position data and provide more accurate downhole position and load data.
