The total number of carbonate ores among the following is .
(i)Argenitie (ii)Calamine (iii)Malachite (iv)Siderite (v)Galena (vi)Magnetite (vii)Dolomite (viii)Cassiterite (ix)Bauxite

Explanation

To solve the question regarding the total number of carbonate ores among the given options, we will analyze each ore and determine if it is a carbonate ore.

### Step-by-Step Solution:

1. **Identify the ores and their chemical formulas:**
- (i) Argenitie: Ag₂S
- (ii) Calamine: ZnCO₃
- (iii) Malachite: CuCO₃·Cu(OH)₂
- (iv) Siderite: FeCO₃
- (v) Galena: PbS
- (vi) Magnetite: Fe₃O₄
- (vii) Dolomite: CaMg(CO₃)₂
- (viii) Cassiterite: SnO₂
- (ix) Bauxite: Al₂O₃·2H₂O

2. **Determine which of these are carbonate ores:**
- A carbonate ore is characterized by the presence of the carbonate ion (CO₃²⁻).
- Checking each ore:
- Argenitie (Ag₂S) - Not a carbonate
- Calamine (ZnCO₃) - Is a carbonate
- Malachite (CuCO₃·Cu(OH)₂) - Is a carbonate
- Siderite (FeCO₃) - Is a carbonate
- Galena (PbS) - Not a carbonate
- Magnetite (Fe₃O₄) - Not a carbonate
- Dolomite (CaMg(CO₃)₂) - Is a carbonate
- Cassiterite (SnO₂) - Not a carbonate
- Bauxite (Al₂O₃·2H₂O) - Not a carbonate

3. **Count the number of carbonate ores identified:**
- The identified carbonate ores are:
- Calamine (ZnCO₃)
- Malachite (CuCO₃·Cu(OH)₂)
- Siderite (FeCO₃)
- Dolomite (CaMg(CO₃)₂)
- Total = 4 carbonate ores.

### Final Answer:
The total number of carbonate ores among the given options is **4**.
