You can use service class directly:

new_resource      = User.new

CopyCarrierwaveFile::CopyFileService.new(original_resource, new_resource, :avatar).set_file
  # :avatar represents mount point (field)

new_resource.save

or you can include CopyCarrierwaveFile module and call copy_carrierwave_file :

class Document
  include CopyCarrierwaveFile  
  mount_uploader :content_file, MyUploader

  def duplicate_file(original)
    copy_carrierwave_file(original, self, :content_file)
    self.save!
  end
