The invention discloses an ore-dressing method for low-grade lead sulfide ore, and relates to the technical field of ore-dressing methods. The ore-dressing method comprises the following steps: pre-working: raw ore is crushed; the ore is ground for the first time to obtain ore powder; the ore powder is mixed with water to obtain ore pulp 1; the ore pulp 1 is …
First, gold and silver recovered at the ore-dressing plant are melted along with lead over a charcoal fire to form an alloy of gold, silver and lead. Next, the alloy is heated in an iron pot covered with ash, and the lead soaks into the ash, leaving only gold and silver. This process is called cupellation, which was introduced from the Iwami ...
Lead-zinc ore usually exists in the form of sulfide ores, such as sphalerite and galena. Flotation is the most commonly used method.. The lead-zinc ore processing solution is adjusted and used in combination according to ore characteristics, metal grade and other factors, such as gravity-flotation, magnetic-flotation, and gravity-magnetic-flotation, in …
The selection of a suitable reagent regime in view of varied mineralogy, physical and chemical characteristics of lead-zinc ore is of critical importance to achieve maximum grade and recovery.

After ore-dressing by flotation, 40 metric tons of bulk concentrate having 18.21 wt. % Pb and 40.20 wt. % Zn is obtained from 250 metric tons of ore per day. Calculate (a) recoveries of lead and zinc to concentrate (%), and (b) the total weight and Pb and Zn percentages (%) of the discarded gangue
Polymetallic sulfide ore dressing by flotation. The copper, lead, zinc polymetallic sulfide ore has a wide variety of minerals, copper, lead, zinc sulfide. The minerals are closely symbiosis. The dissemination particle size is very uneven. It is easy to float and difficult to separate ore. According to the characteristics of the metal ore, the ...
3. Flotation equipment. At present, the lead-zinc dressing plant uses 5A and 1A flotation machines. Due to the flotation machines' long history, equipment operation's high failure rate, and the poor separation index, we replace all the flotation machines with BF flotation machines. BF-2.8 flotation machines are used for priority flotation roughing …
