In which of the following processes is hydrogen used to reduce metal ores?

Step 1: Understand what hydrogen reduction means. It is a process where hydrogen gas is used to convert metal ores into pure metals.
Step 2: Identify metal ores. These are naturally occurring minerals from which metals can be extracted.
Step 3: Recognize that in hydrogen reduction, hydrogen gas reacts with the metal ore to remove oxygen, leaving behind the pure metal.
Step 4: Look for examples of metals that can be extracted using hydrogen reduction, such as tungsten or certain types of iron ores.
Step 5: Conclude that hydrogen reduction is specifically used in processes where hydrogen is the reducing agent for metal ores.
