Question

an ore on treatment with dilute hydrochloric acid produce brisk effervescence. name the type of ore with one example what step will be required to obtain metal from the enriched ore? also write the chemical equation for the reaction involved in the process ​

Answer 1

Explanation:

the brisk effervescence is due to liberation of CO2 from carbonate ores .

generally calcination is used for this purpose .

take ex of calamine ZnCO3 which first convert into ZnO liberating CO2 during calcination

and then will reduce to Zn by coke.

Answer 2

Answer:

When an ore on the treatment with the dilute hydrochloric acid produces brisk effervescence to produce a colorless and odorless gas then the ore should be carbonate ore. The operation required to obtain metal from it will be a calcination process. Hence, the given ore is a carbonate ore.
