"track-type mobile crusher" should be "track-type mobile crushers" for consistency with plural form. 2. "Best suited for sites with reliable electrical power" - "Best" should not be capitalized in the middle of a sentence. 3. "CIP vs. CIL: Key Differences in Gold Cyanidation Processes" - "Key Differences" should not have "Key" capitalized as it is not a proper noun. 4. "Gold Ore - 7 Types and Extraction Methods" - The hyphen should be a colon, as in "Gold Ore: 7 Types and Extraction Methods". 5. "Demand(multiple):" should have a space before the parentheses, "Demand (multiple):". --- 【第 4 段建议】: 1. "rials (brochures, catalogs）" - 应为 "materials (brochures, catalogs)"，花括号使用错误。 2. "WhatsApp:+86 13761974616" - 应在“WhatsApp:”和“+86”之间添加空格： "WhatsApp: +86 13761974616"。 3. "0086-21-58386189 0086-21-58386176" - 应该在两个电话号码之间添加换行或分隔符，以增强可读性。 4. "EPCO Service" - 正确拼写应为 "EPC Service"。 5. "Life-cycle Service" - "Life cycle Service"更常见。 其他部分无错误。
