Can't remount the encrypted partition on Mac primary drive

This machine is used by other people, so I needed a safe place to keep some private information. If not, it seems like all I need to do is make sure that no one else has administrator privileges, make a different user account specifically for my sensitive work, and that should take care of it. I ran an external clone and partitioned my primary drive to create an encrypted partition as a test. The device is a 2TB OWC Mercury Extreme Pro 6G Media. I partitioned about 200 GB and called it Secure. In order to try to remount the partition, I next unmounted it. I tried Disk Utility->File->Unlock, but I was unable to find any results at all. Any suggestions?

When the newly added partition on your Mac primary drive can not be mounted, you can retry to force mount it again in Disk Utility or use Terminal command.

Before macOS Catalina, you can only choose to partition the container on your Mac device. The encrypted drive should be automatically mounted when you check it in Disk Utility. If not, you can select the partition and click the Mount button in Disk Utility's toolbar, or open Terminal and run the command diskutil mount /dev/disk1s2(replace the drive identifier with yours) to force mount the drive.

If you partition the Mac primary drive and encrypt it for data security, you can also choose password-protect files or folders on Mac to prevent other Mac users from accessing. In this way, you don't need to partition the drive. On macOS Catalina and later, you can choose add an encrypted-APFS volume to the container instead of partitioning, the APFS volumes share the free available space within the container.
