实现代码：

func NewAddress(strPrivKey string) (string, error) {
	var (
		uncompressPubKey []byte
		pubKeyHash256 []byte
		err error
		buf []byte
	)
	if buf, err = hex.DecodeString(strPrivKey); err != nil {
		return "", err
	}
	privKey := secp256k1.PrivKeyFromBytes(buf)

	//拿公钥（非压缩公钥）来hash，计算公钥的 Keccak-256 哈希值（32bytes）
	uncompressPubKey = append(privKey.PubKey().X().Bytes(), privKey.PubKey().Y().Bytes()...)

	//计算公钥的Keccak256哈希值
	pubKeyHash256 = common.Keccak256Hash(uncompressPubKey)

	//取上一步结果取后20bytes即以太坊地址
	address := string("0x")+hex.EncodeToString(pubKeyHash256[len(pubKeyHash256)-20:])

	return ToValidateAddress(string(address)), nil
}

测试代码：

func TestNewAddress(t *testing.T) {
	var testcases = []struct {
		privk string
		address string
	} {
		{
			"E452FE5BB764BE2F3E030B6CE5C16E7A68BB341D0D2FDE13AAE5347690F12B52",
			"0x50352B904445576242444bc1924e93e61090738C",
		},
	}

	var (
		got string
		err error
	)
	for _, oneCase := range testcases {
		if got,err = NewAddress(oneCase.privk); err != nil {
			t.Error(err)
			return
		}
		if got != oneCase.address {
			t.Error("new address error")
			t.Error("want: ", oneCase.address)
			t.Error("got: ", got)
			return
		}
	}
}
