The concentration of ions like zinc will increase with time, and the concentration of the copper(II) ions in the solution will fall. For every zinc ion going into solution there will obviously be one fewer copper ion formed. (See the next note if you aren't sure about this.)

The zinc oxide is separated from the other calcines using sulfuric acid. ZnO H2SO4 → ZnSO4 H2O. The zinc is dissolves leaving iron or lead or silver precipitates which are removed. Remaining impurities in the zinc solution are removed using zinc dust. The purified solution is then electrolyzed into high-grade zinc.

Because its position in the reactivity series of metals, zinc can be 'just' extracted using carbon (coke) in a high temperature smelting furnace. it is a sort of displacement reaction. Zinc is extracted from either zinc blende/sphalerite ore (zinc sulphide) or sometimes calamine/Smithsonite ore (zinc carbonate).

A small piece of zinc metal is then added to the hydrochloric acid. When the zinc is introduced to the hydrochloric acid, it rapidly bubbles and produces hydrogen gas. If a scientist puts a balloon over the flask, it will capture the hydrogen gas and expand. The interaction of the hydrochloric acid and zinc is called an oxidation-reduction reaction.
