In explanation, yeah, gold is dissolved, but only in the proximity of the anode (the part(s) being stripped), at which time it quickly is precipitated as the familiar black slimes. Sulfuric acid, alone, can not hold gold

Extraction of Gold

In the electrolytic precipitation of the gold an iron anode and a sheet-lead cathode are employed, the current-density being very low, about 0.5 amp. per sq. metre. The gold is deposited on the lead, and after removal of this metal still contains a considerable proportion of both lead and silver.

Electrolytic Limescale Inhibitors Scalemaster

Scalemaster® Electrolytic Limescale Inhibitors prevent limescale build-up by adding a small trace of zinc to the water. This has the effect of suppressing limescale formation by bonding to the dissolved calcium ions which then require more energy for precipitation. Any micro-crystals which form are then washed away by the water flow rather than adhering to Electrolytic Limescale
