Final answer:
Both lead and zinc are formed as precipitates during the formation of minerals through the process of precipitation.
Step-by-step explanation:
In the formation of minerals, both lead and zinc are formed as precipitates. The step in the formation of these minerals is the process of precipitation, where dissolved substances in a solution come together to form solid particles. When certain conditions are met, like changes in temperature or concentration, the dissolved lead or zinc ions combine with other ions in the solution, resulting in the formation of solid precipitates.
